This investigation was carried out at Horticulture Research Institute Orchard. AgricultureResearchCenter during the two successive seasons of 2005/2006 and 2006/2007 to study the effect of different treatments on germination and seedling growth of Annona sequamosa L. (Balady spp.) The treatments used were soaking in water, GA3, fungicide and EM. The obtained results showed that, EM treatments increased germination percentage close to GA3 treatments and fasted rate of germination as compared with untreated treatment (control). Moreover, EM treatments increased stem length and diameter, number of leaves/plant, leaf area and root length, as well as stem, leaf and root fresh and dry weight. Leaf chlorophyll content insignificantly differed between EM and GA3 treatments. Diluted EM treatment was more effective than concentrated one in this concern. Anatomical study of Annona sequamosa seed showed that, embryo of fresh extracted seed was not yet complete differentiated and it fully developed when seed stored for long time, so germination of fresh seeds were uneven and irregular. In addition, morphological structure of seed show that water can be enters to seed through hillum.

The present study was conducted at the Farm of the Rice Research and TrainingCenter, Sakha, Kafr El-Sheikh, Egypt, during 2000 to 2007 rice growing seasons. Five rice varieties, namely Giza 171, Giza 175, Giza 176, Giza 181 and GZ 1368-S-5 were the most widely grown Japonica and Indica rice varieties in Egypt, during the last period, possessed at that time many positive agronomic characteristics (e.g., wide adaptability, high yield potential, resistance to multiple diseases, and pests and good grain quality. But now, it has some drawbacks in its characters that make it ideal genotypes for identifying mutational changes traits for agronomic importance. Dry seeds of the above mentioned varieties were treated with different doses of gamma rays (100,200,300,400,and 500 Gy), at the National Center for Radiation Research and Technology, Nasr City, Cairo, Egypt, for raising M1 generation. M1 plants were established by transplanting in 2000 season. Seventy seven independent lines have been advanced to M5 generation, enabling evaluation of quantitative traits by replicated trials and promising lines were selected and tested over three seasons as M6, M7 and M8 generations. Morphological variations at vegetative and reproductive stages including plant type, and yield and its component characters are commonly observed in the five populations. The mutant characteristics identified, so far, consist of better resistance to lodging, blast disease, high yield potential, as well as, early maturity. The results obtained from field evaluation over three years, and, also, through PCR detection, indicated that the induced mutants were differed genetically from their parents. Therefore, these mutants could be used as a donor parents in the rice breeding program and some of them could be recommended to be new rice varieties, suitable to be grown in rice belt in Egypt, such as Giza 175- M13 line.

Hanafy
This experiment was carried out at the Agriculture Experimental Station, Faculty of Agriculture, Cairo University, Giza in two successive seasons of 2005-2007and 2006-2008. The aim of this research was to study the effect of foliar spray with BA and B-9 on the growth and yield of marjoram plant. The plants were sprayed with BA at the rates of 50, 100 and 150 ppm, and B-9 at the rates of 500, 1000 and 2000 ppm in addition to control treatment which sprayed with distilled water. The obtained results can be summarized as follows:
All concentrations of BA or B-9 increased all recorded parameters as compared with the control treatment with significant differences in most cases during the two seasons. In the first season, the highest values of plant height, fresh weight of herb, dry weight of herb, dry weight of leaves and flowering tops, total seasonal yield of dry weight of herb and total seasonal yield of dry weight of leaves and flowering tops were produced from using BA at 150 ppm, while the highest dry weight of stems was obtained from B-9 at 2000 ppm. The lowest values of all recorded characters were resulted in control treatment. In the second season, the highest values of plant height, dry weight of herb and total seasonal yield of dry weight of herb were produced from BA at 100 ppm, whereas the highest values of fresh weight of herb and dry weight of stems were obtained from BA at 150 ppm. Also the highest values of dry weight of leaves and flowering tops and total seasonal yield of dry weight of leaves and flowering tops were resulted in B-9 at 500 ppm. Generally, in combined analysis BA at 150 ppm was the most effective treatment in increasing total seasonal yield of dry weight of herb and total seasonal yield of dry weight leaves and flowering tops. Different cuts as a general mean had a significant effect on all recorded parameters in the two seasons. In the first season, the highest values of plant height and fresh weight of herb were produced from the second cut. Also, the highest values of dry weight of herb, dry weight of leaves and flowering tops and dry weight of stems were produced from the third cut. In the second season, the highest values of fresh weight of herb, dry weight of herb, dry weight of leaves and flowering tops and dry weight of stems were obtained from fourth cut, whereas the highest value of plant height was produced from the first cut. The interaction between the growth regulators (BA or B-9) and the different cuts increased all recorded parameters as compared with the control in any cut during the two seasons with significant differences in most cases.

M.
Hanafy
This research was conducted at the Agriculture Experimental Station, Faculty of Agriculture, CairoUniversity, Giza in two successive seasons of 2005-2007 and 2006-2008. The aim of this research was to study the effect of foliar spray with BA and B-9 on essential oil production and chemical composition of marjoram plant. The plants were sprayed with BA at the rates of 50, 100 and 150 ppm, while B-9 at the rates of 500, 1000 and 2000 ppm in addition to control treatment which sprayed with distilled water. The obtained results can be summarized as follows:
BA at the rates of 50, 100 and 150 ppm or B-9 at the rates of 500, 1000 and 2000 ppm increased all recorded parameters as compared to control treatment with significant differences in most cases during the two seasons. In the first season, the highest value of essential oil percentage was produced with B-9 at 1000 ppm, while the highest values of essential oil yield were obtained with BA at 50, 150 ppm and with B-9 at 1000 ppm treatments. In the second season the highest values of essential oil percentage and essential oil yield were produced with BA at 50 and 100 ppm, respectively. The major essential oil components were linalyl acetate and terpinen-4-ol. The highest percentage of linalyl acetate was detected in the oil of the plants sprayed with B-9 at 1000 ppm in the two seasons, while in the first season, the highest percentage of terpinen-4-ol was found in oil of the plants sprayed with B-9 at 500 ppm as well as the highest percentage of terpinen-4-ol in the second season was produced from control treatment followed by B-9 at 500 ppm. In the first season, the highest values of chlorophyll a, b and carotenoids were produced with BA at 50 ppm, B-9 at 2000 and 500 ppm, respectively. While in the second season, the highest values of chlorophyll a, b and carotenoids were obtained from B-9 at 2000 ppm, BA at 150 ppm and BA at 150 ppm, respectively. The highest values of total carbohydrates percentage were resulted in B-9 at 2000 ppm in the two seasons. In the first season, the highest total seasonal yield of essential oil was obtained from B-9 at 1000 ppm, while in the second season, the highest value was produced from BA at 100 ppm. Generally in combined statistical analysis B-9 at 1000 ppm was the most effective treatment in increasing total seasonal yield of essential oil. The lowest values of all recorded parameters were produced from the control plants in the two seasons. Different cuts as general mean had a significant effect on all recorded parameters in the two seasons. The highest values of essential oil percentage, chlorophyll a, b and carotenoids were produced from the third cut in the two seasons. Also, the highest values of total carbohydrates percentage were produced from the second cut and third cut in the first and second seasons, respectively. The highest values of essential oil yield were obtained from the third cut and fourth cut in the first and second seasons, respectively. The interaction between the growth regulators (BA or B-9) and the cuts increased all recorded parameters as compared with the control in any cut during the two seasons with significant differences in most cases.

The in vitro response of shoot tip and epicotyl explants from Volkamer lemon Citrus rootstock (Citrus volkameriana Ten) coupled with shoot tip micro-grafting were observed for the first time. Further analysis was performed to verify the in vitro shoots and roots proliferation in these explants under different treatments. It were observed there different patterns of morphogenic shoots and roots gradient between the two tested explants noticed. These different patterns were influenced by factors related to explants type and the composition of the culture medium either for shoots or roots proliferation. The epicotyls could be used as source of explants for micro-propagation of Volkamer lemon to improve the efficiency of shoots and roots production with higher qualities.
Culturing medium to in vitro best shoot proliferation was MS (1962) basal medium at full strength supplemented with BAP at 1.5mg/L and Kin at 1.00 mg/L plus a fixed 0.50 mg NAA/L. The statistical analysis technique used to indicate the effect of each growth regulator applied either solely or in combinations confirmed the superiority of BAP during proliferation stage as the limited factor affecting proliferated shoot characteristics on both explants type. Medium to best in vitro rooting was that of the same basal medium containing IBA and NAA at 2.00mg/L each plus a fixed 0.50 mg Kin/L.
Micro-grafting study of Washington navel and Valencia scions onto Volkamer lemon rootstock through the measurements of three parameters, are known to be good measures for evaluating the graft compatibility between the two partners, obviously cleared that Valencia scion onto this rootstock is more compatible than Washington navel scion onto the same rootstock.

This investigation was carried out during two successive seasons of 2004 and 2005 to study the effect of fertilization by using two types of organic manures, i.e. cattle or town refuse at different levels (50, 75 and 100%) from its recommended dose with or without biofertilizers mixture, i.e. microbien and phosphoren in combination with 50% mineralized NPK on growth, chemical composition as well as yield and its quality of Grand Nain banana plants in comparison to banana plants only fertilized with mineralized 100% NPK of the recommended dose. The best results obtained that from banana plants inoculated and fertilized with cattle manure at rate of 100% . In addition, biofertilizers with organic manure improved growth, chemical composition as well as fruit yield and its quality. Increasing the rate of either organic manure with or without inoculation had a positive increment on all studied parameters, especially with the high rate. Chemical constituents of Grand Nain banana fruits were greatly improved as a result of using N in both organic and mineral sources rather than adding N completely via only mineral source. Organic fertilization with cattle or town refuse had a favorable effects on fruit quality since in increase finger weight and concentration of soluble solids and total sugar as well as decreasing concentration of starch and nitrate in fruits except the high rate of town refuse. Organic fertilization by using cattle manure at the rate of 100% combined with 50% mineralized NPK of the recommended rate and inoculated by biofertilizers gave the best results with all studied characteristics of Grand Nain banana plants .

This work was carried out during the two successive seasons of 2007, 2008 on white sapote casimiroa edulis, Llave&Lex. The Fruits were obtained from El –kanater horticulture Research station, to determine the optimum maturity stage of fruits alongside assessment of fruit quality under various circumstances of storage. The obtained data revealed that fruit reached maturity stage after 117-121days from full bloom, rind color changed from dark green to light green and pulp color became white cream and TSS reached to 13.3-13.8 in both seasons of study .There was obvious relation between storage temperatures and ripening process .The fruits held at room temperatures 35°C and 65%RH ripened after 5 days, however fruits held at 10°C &5°c and 90%RH, this period reached 15 and 25 days respectively. Fruits held at 0°C did not ripen till 30days at cold storage and could be transfer to room temperature 35°C to reach ripening stage. The headspace volatiles of fresh white sapote Casimiroa edulis and of those exhibited the best quality after storage at different temperature were isolated and subjected to gas chromatography – mass analysis. A total of 23 component were identified in casimiroa aroma including esters (8), alcohols (7), aldehydes (3), terpenes (4), and (1) ketone. Esters and alcohols comprised more than 85% of the total volatiles in casimiroa fruits at mature and in all stored samples .The major esters were ethyl butyrate, ethyl acetate and hexyl acetate while the major alcohols were ethanol and 3-methyl butanol. The results revealed no remarkable changes between volatiles of mature and stored samples. However, sample 3 that stored at 10°C for 15 days comprised the highest yield of ethyl butanoate (43.4%) which possessed sweet and furity aroma and considered as index of good quality. In general storage of casimiroa fruits at different temperatures 5&10 and 35 °C caused their ripening which lead to high concentrations of ethyl butyrate and ethanol. These compounds are responsible for the consumer acceptability of casimiroa fruits.

Verticillium wilt, caused by Verticillium dahliae, is the most serious disease in olive cultivation areas in Egypt. Thirty six (36) isolates of V. dahliae from olive (Olea europea L.) trees originating from eight regions of Egypt were taken for vegetative compatibility analysis using nitrate non-utilizing (nit) mutants. One isolate did not produce a nit mutant. Thirty five (35) isolates yielded nit mutant, they were tested for vegetative compatibility by observing heterokaryon formation among complementary nitrate-nonutilizing (nit) mutants. Among 569 chlorate-resistant sectors obtained, only 370 were Nit mutants. Three types of Nit mutants were obtained (Nit1”251”, NitM”101” and Nit3”18”) on the basis of the fungal phenotype. Nit1 mutants were the most frequent (67.8%), followed by NitM (27.3%) and Nit3 (4.9%). Based on their ability to form heterokaryons, all 35 olive pathogenic isolates were grouped into a three vegetative compatibility groups. where include VCG1 five isolates “1, 2, 6, 9, 11”, VCG2 twenty one isolates” 3, 4, 5, 7, 8, 12, 19, 27, 20, 16, 10, 13, 14, 15, 17, 21, 22, 23, 25, 26, 24” and VCG3 nine isolates “18, 28, 29, 30, 31, 32, 33, 34, 36.

This investigation was conducted during two successive seasons (2005/2006 and 2006/2007) on the first and second ratoons of Williams banana plants grown in a sand clay loam soil under flood irrigation conditions in a banana orchard located at El-Kanater Research Station, Kalubia Governorate. The plants received recommended dose (RD) of mineral N only/or between its different rates (75, 50 and 0% N of RD) and organic N in the form of Nile Compost (NC) and Chicken Manure (CM) as well as Microbein bio-fertilizer (M).
The obtained results clarified that all used treatments were effective in improving growth, yield and fruit quality in comparison with 100 % N either in the form mineral (control) or in the form organic manure (Nile Compost or Chicken Manure) of Williams banana. It was also noticed that the combined treatment of 50 % mineral N + 50% N in the form of compost with Microbein biofertilizer gave best plant vegetative growth parameters (circumference and height of pseudostem, number of green leaves and leaf area( as well as leaf chemical content expressed as an increase in percentages of nitrogen, phosphorus and potassium. In addition, it noticed that the same combined treatment had the highest values of yield and its components such as bunch weight, number of hands/bunch, average hand weight and number of fingers/hand. Also, it noticed that the same combined treatment improved physical properties of fruits expressed as average finger weight, average finger length, average finger diameter and pulp (%) as well as chemical properties of fruits such as, increasing the percentages of TSS, reducing and total sugars while decreased the percentage of acidity.
In general, the results proved that using of 50 % mineral N + 50% N in the form of compost + Microbein biofertilizer are the most superior treatments for increasing vegetative growth, yield and its components as well as fruit quality of Williams banana. Hence, It could be concluded that, minimizing the use of chemical nitrogen fertilizer to half of recommended dose through addition of 50 % mineral N + 50% N in the form of compost with Microbein biofertilizer.

Salinization of both salt-sensitive and salt-tolerant lettuce plants with increasing doses of NaCl, throughout the entire period of experiment induced significant increases in both glucose and fructose contents and significant decreases in sucrose content. In salt-tolerant Eskandrany cultivar, sucrose content was found either to increase significantly (at 3 dS/m NaCl), non-significant decrease (at 7 dS/m NaCl) or to decrease significantly (9 dS/m NaCl). Organic acid content (citric, oxalic and keto acids) showed significant increases in both salt-sensitive and salt-tolerant lettuce cultivars as compared with control. Proline and glycine amino acids content of both cultivars, salinized with increasing doses of NaCl, throughout the entire period of the experiment, showed significant increases. In all cases, the magnitude of accumulation of all metabolites determined was most pronounced in salt-tolerant lettuce cultivar. The results were discussed in relation to the mechanisms of salt tolerance in plants.

The combination of urea or ammonium sulphate (A\so4) with farmyard manure (FYM) as well as using anyone of them alone as a source of nitrogen for rice cultivation was studied at Rice Research and Training Center (RRTC), Sakha, Kafr EL-Sheikh Governorate, Egypt during 2005 and 2006 seasons. The results revealed that, grain and straw yields and yield components significantly increased with the application of nitrogen sources in comparison to unfertilized check. There were no significant differences between urea and ammonium sulphate on the above mentioned characters. The ability of FYM alone to provide nitrogen is insufficient because of its lower N-content and higher C\N ratio. Generally, the combination of urea or ammonium sulphate with FYM in 75:25 ratio and full dose of mineral fertilizer either urea or ammonium sulphate gave the same effect of yield and yield components of rice. Under this study we can recommended that application of urea or ammonium sulphate or its combination with FYM in ratio 75:25 gave the best grain yield of rice.

Two field experiments were carried out at the Experimental Farm of Gemmeiza Agricultural Research Stations during 2007 and 2008 seasons to study the effect of row spacing, i.e. (60,70 and 80cm apart) and plant density, i.e. (20000, 25000 and 30000 plants/fed.) on growth, yield and yield components of two maize hybrids, i.e. (S.C125 and S.C162). A split-split plot design with four replicates was used in the two experiments.
Results showed that increasing ridge spacing significantly recorded No. of days two 50% tassling and silking , plant and ear heights were in the same direction planting on 80 – cm ridge was associated with a significant increase in ear length , No. of kernels/row, 1000 kernels weight and grain yield (ard/fed).
On the other side, plant density of 25000 plant/fed was associated with the highest grain yield and its component as soon as it is considered of the optimum environmental.
Single cross 125 was earlier than single cross 162 of days to 50% tassling and silking. S.C. 125 had the best effects of plant and ear height towards low ear position, 1000 kernels weight, S.C. 162 gave the highest values of No. of ear length kernels/row and grain yield. (Ridge spacing x plant density interaction was significant for No. of days to 50% tassling and silking, plant and ear heights, No. of kernels/row. Plant density x hybrid interaction was significant for plant height, ear length, 1000 kernels weight (g) and grain yield ard./fed).
This investigation showed that planting on 80- cm rows at plant density of 25000 plants/fed (25- cm between hills) in order to obtain the highest grain yield. This would also facilitate using the mechanization and saving costs, time, and effort.

This study was carried out in Experimental Station of Forestry and Wood Technology Department, Fac. Agric., Alexandria Univ., El-Shatby, Alexandria, Egypt in 2006- 2008. The study dealt with the effect of spacing and time of cutting on the growth, yield, nutritional value of soft edible parts for animals and seed, some physical and anatomical properties of the wood of Leucaena leucocephala trees. Four month old aged transplants of L. leucocephala transplants were planted in 0.5 × 0.5 (D1) 1.0 × 1.0 (D2) and 2.0 × 2.0 (D3) m apart. Growth parameters (Pole height and stem diameter) were monthly determined. Plants were cut after one year (Y1) and two years (Y2) of planting date. To study the effect of spacing and age of plants, RCPD design was followed. The most important results can be presented as follows: total dry biomass was 14.1, 12.74 and 11.15 ton/ feddan for D1, D2 and D3 treatment of cut plants after one year of planting date (Y1) and 30.66, 28.53 and 27.30 tons/ feddan for those cut after 2 years of planting date (Y2), respectively. Dry weight of soft-edible parts (as forage for animal) was 5.03, 4.25 and 3.58 ton/ feddan of D1, D2 and D3, respectively in " Y1", while it was 10.33, 9.63 and 8.70 tons/ feddan in " Y2".Analysis of edible parts of plant revealed that it was contained 1.07, 0.88 and 0.74 ton of crude protein/ feddan in D1, D2 and D3 of Y1 plants, respectively, while it was amounted for 2.26, 2.04 and 1.85 tons of crude protein/ feddan in Y2. However, moisture content of wood was averaged 96.18 and 106.91% for Y1 and Y2, respectively. Fiber length was 1.1 and 1.21 mm for Y1 and Y2, respectively. Microscopic examination of anatomical elements (vessels, fibers, rays and longitudinal- parenchyma) distribution revealed that there were no significant influences of spacing (D1, D2 and D3) and age of cut (Y1 and Y2) on the percentage of each element. Annual cut recommended for forage production pulp paper and particle board, fuel production. It is recommended also to extend plantation of L. leucocephala to capitalize on its environmental and economic benefits.

The Egyptian olive industry requires new selected genotypes to address the need of modern production. In order to produce new genotypes for table olives, olive oil, or dual purpose varieties, breeding program was initiated in Egypt in 1994, by crossing between local and foreign cultivars.
During three years progenies from crosses between cvs. (Chemlali x Aggizi), (Aggizi x Kalamata) and (Aggizi x Koronaiki) were evaluated. The progenies have been analyzed for traits of the tree (shoot length, shoot thickness, number of nodes/shoot, internodes length (cm), the leaves (average number of leaves/shoot, leaf surface area, leaf shape) , flowering ( flowering time , the length of inflorescence , number of total flowers/inflorescence, number of perfect flowers/ inflorescence, number of staminate flowers/ inflorescence, sex ratio, and fruit set/m,), fruiting (production, fruit shape, fruit weight, stone weight, flesh weight ,flesh/stone, moisture and oil content( oil percent in fresh weight and oil percent in dry weight) and rooting ability .From the obtain data it can be concluded that some valuable selections have been resulted. Such Progenies were No.24 ,26, 27and 31 for table olive; progenies No 7, 10, for oil and No. 33, 38, 39 for dual purpose. Conclusion
Thus, all the best selected progenies were propagated and planted in three locations, to evaluate their performance in different geographical areas. Performance included i.e., tree growth, yield, fruit characteristics, oil content and oil compositions in fatty acids. There comes the necessity to study quantitative and qualitative traits of olive production.

STUDY ON COMPATIBILTY PARAMETERS BETWEEN THOMPSON SEEDLESS, SUPERIOR, FLAME SEEDLESS AND KING RUBY GRAPE CULTIVARS ONTO HARMONY ROOTSTOCK.
M.
Mostafa
The present study directed in two successive seasons of 2006 and 2007 to assess some of compatibility parameters measured between four commercial Grape cultivars grafted onto Harmony rootstock ; percentage of grafting success, vigor of grafts, lignin content of cell wall at union zone and NPK content of leaf petioles. An apparent increase in values of these characteristics that may be considered as good indicators to the compatibility between Superior cultivar onto Harmony rootstock, Superior surpassed the other grape cultivars and showed more compatibility. Thompson seedless and Flame seedless onto Harmony were intermediate in this respect. However, King Ruby cultivar onto Harmony showed less compatibility. King Ruby/Harmony was the highest in NPK content % in its leaf petioles than other cultivars tested in this study during the two seasons. Moreover, Thompson seedless/Harmony gave significant response in leaf surface area / No. of leaves / shoot, fresh and dry weight/leaves/shoot of graft combinations followed by Superior/Harmony, Flame seedless/Harmony and King Ruby/Harmony during both seasons of study. In addition, both Flame seedless and King Ruby onto Harmony rootstock gave the highest values of lignin content % in union zone.

This investigation was carried out to study the effect of some natural organic nutrients including compost extract which recently called in agriculture field )compost tea( and chicken manure extract with different concentrations on yield, cluster characteristics, total sugars and nitrate content in berries of Thompson seedless grapevines. Seasonal changes of NPK in leaf petioles during different stages of grapevines were also studied.
Treatment No. 8 (Compost tea (1:10) x chicken manure extract (1:10) gave the highest values of yield (kg/vine), cluster weight (g) and volume (ml) and also for total sugars and nitrate content of berries. From the other side, the best treatment for producing safety fruits for using human kind was the treatment No. 9 {(Compost tea (1:20) x chicken manure extract (1:20)}, which gave satisfactory yield and cluster weight and volume as well as total sugars (significantly more than values of control treatment), besides it produce the lowest nitrate contents of berries, that means its more safety for human use.

PHOTOSYNTHATE REQUIREMENTS FOR NITRATE UPTAKE AND REDUCTION IN ROOTS OF Vicia faba L. SEEDLINGS
M.
Wasfi
Nitrate uptake was examined in the roots of 15-day old nitrogen depleted broad bean (Vicia faba L.) seedlings during a 10 h. exposure to 7 mM KNO3. The seedlings were subjected to partial defoliation, thermal treatment at stem bases and girdling.
The loss of nitrate from the medium during incubation of the seedlings indicated that about 30% of the nitrates were absorbed during the first 5 h. It was evident that the energy expanded for nitrate uptake and reduction came from the tops, since partial defoliation, thermal treatment and girdling restricted nitrate uptake and reduction. The data are interpreted as indicating a close interrelationship between nitrate uptake and reduction and carbohydrate metabolism, particularly in relation to the export of photosynthate from the tops to the roots.

Two pot experiments were conducted at the Experimental Station and in the Laboratory of Vegetable and Floriculture Department, Faculty of Agriculture, Mansoura University during the two successive seasons of 2005/2006 and 2006/2007 to study the effect of GA3 and ABA at different concentrations on vegetative growth, yield and chemical composition of khella plants growing under different potassium fertilization rates.
The obtained results exhibited that khella plant height, shoot dry weight and content of photosynthetic pigments in the leaves as well as N, P and K concentrations in the shoots were increased with increasing potassium fertilization levels and the highest values were recorded when the plants received the high level of potassium (45 kg/fed.).
GA3 and its interactions with potassium fertilization increased significantly the plant height, shoot dry weight and N, P and K concentrations in the shoots, while the content of photosynthetic pigments in the leaves was decreased. On the other hand, ABA and its interactions with potassium caused a decrease in the previous parameters except for the content of photosynthetic pigments in the leaves which was increased.
Regarding number of umbels and fruit yield per plant as well as the content of khellin and visnagin (%), data showed that potassium fertilization and ABA as well as their interactions significantly increased these parameters. However, GA3 application alone caused a decrease in number of umbels and fruit yield per plant as well as the principle constituents (%). Meantime, GA3 with potassium fertilization at either 30 or 45 kg/fed. increased the fruits content of visnagin.
