Mansor
This investigation provides a new method for produced dyed yarns of low cost and sufficient quality to be used for garment manufacture using some Egyptian cotton varities of different grades and consequently different Maturity percentages in combination with combed cotton waste in different ratios in open end (O.E) spininig process. In this study we tried to find facilities looking to upgrade the disposal comber noils into medium dyed yarns. We succeeded in choosing Giza 88 cultivar combing noils to blend withboth Giza 80 and Giza 90 as a long Upper Egypt cultivars which described as coarse and short as compared with the other Egyptian cultivars and their creamy color similar to the combed waste. Measurements of fiber maturity percentage, Fiber and yarn properties, dye ability, andcolor difference propertiesof the produced blends were studied. The results obtained revealed that the best values for all the fiber and yarn characters considered that open end was the favorable system for this investigation. The results show that the micronair reading, hair weight (H.W), upper half mean, uniformity index, color strength (K/S) and color difference showed decrease as the ratio of the cotton varieties decreased.

This study was conducted to investigate combining ability and gene action of rice hybrids and their parental lines. Four CMS lines as female parents and three restorers' lines as male parents were hybridized to produce 12 F1 hybrids were used in a line x tester mating design. the resulted genotypes were used to estimate combining ability, heterosis, and gene action for yield and yield components characters. The results indicated that most characters were largely governed by additive gene action. General and specific combining ability effects of the genotypes for the characters under study were estimated. The results showed that the characters were controlled both general combining ability (GCA) and specific combining ability (SCA) . The CMS and restorer lines showed variable effects for GCA. The study also indicated the presence of heterosis over the better parent (BP), Mid-parents (MP) and over the best check variety Giza 178 for nine characters of yield and yield components.

The effects of enhanced UVA (320-380), UVC (280nm) and SDS, as mutagenic substances, on growth parameters and certain metabolic changes, during vegetative and flowering growth stages of garlic (Allium sativum var. Seds 40) were investigated. Root length, shoot length, fresh mass, dry mass accumulation and leaf area in garlic, treated with UV- radiation (A and C), and SDS (0.1 M and 0.3 M) as mutagenic substances, throughout the entire period of the experiment, showed significant variable changes below the control levels. Photosynthetic pigments (chl a, chl b, carotenoids, total chl a+b, and total pigment) contents of the variously treated garlic plants showed significant changes as compared with control plants throughout the duration of the experiment. The ratio of chl a / b showed variable changes in UV- and SDS- treated plants in relation to control. UV- absorbing compounds (total phenolic compounds and anthocyanins contents) of the UV- and SDS- treated garlic plants, showed significant increase above the control levels during vegetative and flowering growth stages. As compared with control nucleic acid levels, nucleic acid contents (DNA and RNA) of UV- and SDS- treated plants, at vegetative and flowering growth stages, showed significant decrease.

COMBINING ABILITY, GENE ACTION AND HERITABILITY OF SOME DIALLEL VARIETAL CROSSES IN BREAD WHEAT UNDER NORMAL IRRIGATION AND DROUGHT CONDITIONS
M.
Abdel-Moneam
Five bread wheat varieties representing different agronomic characters were crossed in a half-diallel model in 2005/2006 season. The five parents and their 10 F1 crosses were evaluated under normal irrigation and drought conditions in 2006/2007 season to study the mode of gene action for some wheat traits.
Mean squares of genotypes, general and specific combining ability were significant for all traits under normal and drought conditions, except specific combining ability for plant height at normal irrigation. The best combiners at both environmental conditions for of days to heading, days to maturity (earliness), flag leaf area and spikes number/plant was Sakha61; for plant shortness were Sakha8 and Sakha-93; for kernels/spike, 100-kernel weight and grain yield/plant were Gemmeiza9 and Giza168. These results indicated that these genotypes could be considered as good combiners for improving these traits. The best combinations at both conditions for days to heading was Giza168×Gemmeiza9, for days to maturity was Sakha61×Gemmeiza9; for flag leaf area was Giza168× Sakha61; for plant height (shortness) and 100-kernel weight was Sakha61×Sakha-93; for spikes/plant and kernels/spike was Sakha8×Gemmeiza9; for grain yield/plant were Giza168 x Gemmeiza9 at normal condition and Sakha-93×Gemmeiza9, at drought condition. These crosses could be selected and used in breeding programs to improving these traits.
Both additive and dominance gene effects were significant for most traits at both conditions. The results showed that the role of partial dominance gene effects in controlling all traits under both studied conditions, except grain yield/plant at normal condition, 100-kernels weight at drought stress condition and spikes number/plant at both conditions, which controlled by over dominance gene effects. Each one of studied characters were governed at least by one gene group, except days to maturity and 100-kernel weight at normal condition; flag leaf area and grain yield/plat at stress conditions, which were governed at least by two gene groups. Grain yield/plant at normal condition and spikes number/plant at stress condition were governed by at least three gene groups. Also, spikes number/plant at normal condition was governed by at least four gene group. Heritability in narrow sense (h2n.s) estimates were moderate or high for all studied traits at both conditions, reflecting the role of additive gene action in governing these traits, therefore selection for these traits could be applied in early segregating generations, except spikes number/plant at both conditions, which had low values of heritability in narrow sense.
The parents Sakha-61 and Giza-168 and Gemmeiza-9 could be used in breeding for drought tolerance. Selection for days to heading, days to maturity, flag leaf area, plant height and kernels/spike at both conditions and for grain yield/plant at drought condition may be practiced in early segregating generations to improved bread wheat with respect to these genetic materials.

Two field trials were carried out at El-Gimiza Research Station Farm during 2005/2006 and 2006/2007 seasons to study the effect of spraying potassein-P (30% K2O and 10% P) and three seeding rates (24, 36 and 42 kg/fed) on growth, seed yield, fixed oil, carbohydrate and protein percentages of two varieties (Giza 2 and Giza 30) and two promising strains (16 and 29) of fenugreek plant.
The results showed that fenugreek strain 29 was the latest in flowering and maturity. Strain 29 exceed Giza 2 var., Giza 30 var. and strain 16 in plant height, branches and pods number, 1000 seed weight and protein percentage. Whereas strain 29 and Giza 2 var. recorded the maximum seed and oil yield and carbohydrate percentage. Spraying of potassein-P significantly increased all characters under study than unspraying. Sowing fenugreek at low seed rate of 24 kg/fed significantly increased branches number, seed yield and its components, percentage and yield of oil and protein percentage.
Data showed that the interaction of varieties X seeding rates had significant effects on all studied characters except plant height and oil percentage. All the interactions were significant concerning 1000 seed weight and protein percentage.
GLC analysis of fatty acids showed that the total percentage of unsaturated fatty acids was higher than the value of saturated one in all varieties and strains fixed oil. Linoleic acid was major components of unsaturated fatty acid. Giza 30 variety and strain 29 recorded the highest value of linolenic unsaturated fatty acid.
The best treatment for highest yield of seed and oil was that of sowing Giza 2 var. at low seed rate of 24 kg/fed and spraying with potassein-P while, maximum yield of seed and oil and protein percentage could be achieved by sowing promising strain 29 at 24 kg/fed seeding rate and spraying with potassein-P.

Attia
The present study was carried out in the summer season (2005) to investigate the effect of some drying methods on the quality of basil plant (Ocimum basilicum L.). The sun drying (50oC), shade drying (35oC) and oven drying (40oC). The physico chemical properties of the plant were determined. The results showed that the higher value of volatile oil percentage, methyl chavicol compound and chlorophyll content were noticed by shade drying method, meaning that shade drying method was the best treatment to keep the quality of basil plant as high as possible. On the other hand, sun drying method was the lowest one since it caused a decrease in the plant quality i.e the essential oil content, chemical composition in linalool, methyl chavicol and other main components beside a decrease in its chlorophyll content. Oven drying was a moderate treatment to keep the plant quality. As for microbial load (ML), the three treatments showed insignificant effect and was within the range reported by Egyptian specification standard on dried basil.

Four separated pot experiments were carried out in the open field at the Experimental Station of Vegetable and Floriculture Department, Faculty of Agriculture, Mansoura University during the two successive seasons of 2006/2007 and 2007/2008, as each season contained two periods of growth, to find out the response of six-months-old transplants of Acalypha wilkesiana Müll. Arg., Asclepias curassavica L., Dodonaea viscosa (L.) Jacq. and Tabernaemontana divaricata (L.) R. Br. ex Roem & Schult. to long-term stress of lead (Pb), cadmium (Cd) and nickel (Ni) combinations added as thawing acetate salts to the soil mixture at the rates of 00.00 ppm for each metal as a control, 500 ppm Pb + 50 ppm Cd + 25 ppm Ni for treatment number one (T1) and 2-, 3-, 4- and 5-fold of these concentrations for treatments number two (T2), three (T3), four (T4) and five (T5), respectively. Planting was in 25-cm-diameter black polyethylene bags filled with 3 Kg of a mixture of sand and loam at 1:1 (v/v).
The obtained results indicated that no mortality was observed among Acalypha and Asclepias transplants, as they recorded 100% survival during the two periods of growth in the two seasons, but in case of Tebernaemontana and Dodonaea transplants, such parameter was reduced, especially for the transplants which were exposed to T4 and T5 combinations in the second period of growth. However, survival % of Tabernaemontana transplants was higher than that of Dodonaea. In general, top and root growth of the four shrubs was declined with various significant differences, specially with prolonging growth period under high level of toxic elements, except for Acalypha transplants which gave longer roots than those of control transplants under low and medium concentrations of heavy metals (T1, T2 and T3). However, under high concentrations (T4 and T5), the length of their roots was quite similar to that of control. So, it gave the highest pollution resistance index percentage (PRI %) compared to the other shrubs.
In brief, according to the aforementioned results (in particular survival % and PRI %), ornamental shrubs undergo long-term stress of Pb, Cd and Ni combinations under conditions of the present work should be arranged in the following descending order: Acalypha wilkesiana > Asclepias curassavica > Tabernaemontana divaricata > Dodonaea viscosa.

Four separated pot experiments were carried out in the open field at the Experimental Station of Vegetable and Floriculture Department, Faculty of Agriculture, Mansoura University during of 2006/2007 and 2007/2008 seasons, as each season contained two periods of growth, to detect the effect of long-term stress with lead (Pb), cadmium (Cd) and nickel (Ni) added in combinations as thawing acetate salts to the soil mixture at six rates on chemical composition of six-months-old transplants of Acalypha wilkesiana Müll. Arg., Asclepias curassavica L., Dodonaea viscosa (L.) Jacq. and Tabernaemontana divaricata (L.) R. Br. ex Roem & Schult. grown in 25-cm-diameter black polyethylene bags filled with 3 Kg of a mixture composed of sand and loam at 1:1 (v/v). The chemical analysis of the studied shrubs was conducted two times in the second season only; i.e. at the terminal of October 2007 (first growth period), as well as at the end of October 2008 (second growth period).
The obtained results indicated that chlorophylls a and b, carotenoids, total carbohydrates, N, P and K contents in the leaves of all studied shrubs were progressively decreased with increasing heavy metal concentrations to reach the minimum values in transplants subjected to the highest level of toxic metals with highly significant differences compared to the means of unpolluted ones in most cases of the two periods of growth. An exception was only obtained for transplants treated with the lowest level of heavy metals, as all previous constituents were slightly increased in the leaves of both Acalypha and Asclepias transplants, while in Tebernaemontana and Dodonaea transplants many of them were increased and many others were decreased. In general, prolonging the period of subjecting to the toxic metals stress caused a gradual decrement in the content of aforementioned constituents.
On the other hand, a progressive increase was noticed in the content of Pb, Cd and Ni in the leaves and roots of the four used shrubs with elevating heavy metals concentrations. Moreover, the content of such metals was higher in the roots than in the leaves, and in the second growth period than in the first one. So, the highest content of them was observed in the roots of transplants polluted with the highest level in the second period of growth.
From the above mentioned results, it could be recommended to use Acalypha wilkesiana and Asclepias curassavica transplants to landscape areas suffering from Pb, Cd and Ni pollution, as they absorbed the highest amounts of these metals under the conditions of the present study, followed by Tabernaemontana divaricata then Dodonaea viscose.

A.
Kamal
Two field experiments were performed during the successive seasons of 2006 and 2007 at Talkha district, Dakahlia Governorate, Egypt to determine the effect of gypsum, phosphoreine and rock phosphate rates on growth, chemical composition, yield and quality of sweet pepper plants cv. California wonder.
The main results could be summarized that:
- Application of 4 ton/feddan of gypsum as soil amendments and 1 kg of phosphorein as transplants inoculation with 60 or 90 kg P2O5 of rock phosphate induced a significant effect on root, shoot , total dry weights, N, P and K contents of pepper plant foliage as well as N and P total uptake.
- Additions of gypsum at 4 ton/ feddan and phosphorein at 1 kg/ feddan with 60 or 90 kg P2O5 of rock phosphate showed a significant effect on maximizing average fruit weight, number of fruits per plant, fruit yield per plant, total yield per feddan, fruit flesh thickness, fruit dry weight and fruit TSS.
- Adding 4 ton/feddan of gypsum and 1 kg/feddan of phosphorein with 60 kg P2O5 of rock phosphate increased sweet pepper fruit yield by 56.22 % above control.
In general, this study demonstrated that it is possible to produce highest growth, yield and quality of pepper plants by applying rock phosphate as a cheap phosphorus source; it will be necessary to add gypsum at 4 ton/feddan and 1 kg/ feddan of phosphorein with 60 kg / P2O5 of rock phosphate.

Abd Al-Gaid
Two field experiments were performed during the two successive seasons of 2003 and 2004 at Mansoura Vegetable Research station at El-Baramon, Dakahlia Governorate, Egypt, to study the effects of some calcium sources and levels as a foliar spray applications to reduce the disordered fruits; i.e., cracking and blossom end rot as well as improving fruit yield and quality of tomato cv. GS 12.
The main findings obtained from this investigation showed that:
- Sprayed tomato plants with Ca-nitrate at 1.5 or 2 g Ca /L gave the lowest values of the percentage of cracked fruit types; radial, longitudinal, ring, transversals and total cracked fruits as well as fruits infected with blossom end rot.
- Total marketable yield per feddan was significantly increased and reaches its maximum values by foliar application with Ca-nitrate at 1, 1.5 or 2 g Ca /L.
- Fruit dry matter content was significantly affected by foliar spray of 1.5 g Ca /L of Ca-nitrate compared with all other treatments and control.
- The most effective treatment affected on fruit total soluble solids was that of using 1.5 g Ca /L of Ca-chloride or Ca-nitrate.
- Ascorbic acid content and titratable acidity of tomato fruit did not significantly influenced with all used calcium treatments.
- Foliar application of 2 g Ca /L of Ca-chloride or Ca-nitrate showed a significant enhancing effect on Ca content of tomato fruits.
- Tomato plants which sprayed with 2 g Ca /L of Ca-chloride or 1, 1.5 or 2 g Ca /L of Ca-nitrate were reached the highest total carbohydrate of tomato fruits.
- Nitrate content in tomato fruit was significantly decreased with foliar application of Ca-chloride at 1.5 or 2 g Ca /L followed by using Ca-nitrate at 1.5 or 2 g Ca /L.
It can be recommended that foliar spray tomato plants with Ca-nitrate at 1.5 g Ca /L at the beginning of flowering and repeating every 15 days produce good tomato yield with less percentage from disorders fruits.
In conclusion, this study demonstrated that it is possible to minimize disorders fruits and produce highest yield and quality of tomato by foliar spraying with Ca-nitrate at 1.5 g Ca /L at the beginning of flowering 4 times each 15 day intervals.

This study aimed to investigate the effect of three soil media, three irrigation intervals, three NPK fertilization rates and their interactions on the growth and development of Conocarpus erectus tree as a new plant to the Egyptian environment. This research was carried out during the two successive seasons of 2004 – 2005 and 2005 – 2006.
The obtained results showed significant differences in some investigated characteristics. Clayey soil significantly gave the greatest value of plant height, number of branches per plant but had non significant effect on chlorophyll pigments content. Use of 10 or 15 days irrigation intervals significantly had an effect on plant height, number of branches per plant and chlorophyll pigments content. The addition of NPK at a rate of 5 or 10 gm/plant resulted in significant increase of plant height and number of branches per plant while had non significant effects on chlorophyll pigments content. The interaction treatments showed that generally, clayey medium, 10 or 15 days irrigation intervals and 5 or 10 gm NPK/plant significantly increased the values of plant height while, the mixture medium and 10 or 15 days intervals and mostly 5 gm NPK/ plant significantly affected the value of number of branches/ plant. Results of interaction showed also that clayey medium with 5 days irrigation intervals and 10 gm NPK/ plant significantly increased the chlorophyll pigments content. Clayey soil irrigated every 15 days and fertilized with 5 gm NPK/plant significantly increased the stem diameter when compared with other treatments. On the other hand, dry matter percentage was significantly increased by the use of mixture medium (clay + sand), 5 days irrigation interval and 10 gm NPK/plant.

LECTROPHORETIC ANALYSIS OF SOME HIBISCUS VARIETIES USING PEROXIDASE ISOZYMES AND THEIR GENETIC DIVERSITY
H.
El-Tayeb
Hibiscus (Family Malvaceae), is an evergreen flowering shrub native to East Asia. It is widely grown as an ornamental plant throughout the tropics and subtropics. The flowers are large, generally red in the original varieties, firm and lack any scent. Numerous varieties, cultivar and hybrids are available with flower colors ranging from white through yellow and orange to scarlet and shades of pink with both single and double sets of petals.
Consequently, a greet attention has been focused on hibiscus. On the other hand, isozymes considered to be powerful tool for gene variability. Therefore an attempt was done to estimate peroxidase isozymes activities in five varieties of Hibiscus taken from Antoniades Botanical Gardens, Alexandria. Egypt., and classified as four varieties 1- Athene, 2- Cairo, 3- President, and 4- Saphire for species Hibiscus rosa-sinensis and Red variety for species Hibiscus mutabilis . Such a trait of activity of peroxidase was used in the five varieties under study to regulate genetic diversity.
The result obtained showed that there were a similarity of peroxidase isozymes activities in varieties 1- Athene, 2- Cairo, 3- President, and 4- Sapphire and in contrast, the activities of peroxidase isozymes found to be different in the variety Red since it was found to be more active. The same result observed on genetic diversity since it showed two clusters. Cluster 1 includes four varieties 1- Athene, 2- Cairo, 3- President, and 4- Saphire while cluster 2 includes variety Red.
The importance of such data in the breeding programs is to develop an index for parental selection and the hybridization between different cluster varieties expected to increase the hybrid vigor which can be used in breeding programs.

Nantes cultivar had highest values in plant length, while, Chantnay surpassed in total plant weight, root and shoot weight and shoot : root ratio, but Japanese gave the largest root diameter and length. Compost application resulted in increasing growth parameters, the highest values were obtained with 6 ton /fed. Also, bio-fertilizer application increased growth characters.
Nantes cultivar showed the highest values of yield, followed by cvs. Japanese and Chantenay respectively. Compost application at rat of 6 ton./fed. showed positive increasing in total and marketable yield. Also, bio-fertilizer treatment significantly total produced increased yield.
Chantenay cultivar had the highest content of K, Ca and carotene, but cv. Nantes showed significantly less content in Na and CL than Japanese cultivar, and the highest content of carbohydrates. Compost application at rat of 6 or 9 ton/fed. resulted significant increase in K and Ca content, also, the same rates increased carotene and carbohydrates content. On the other hand, application of 9 ton/fed. compost gave the lowest values of Na and CL content. Bio-fertilizers treatment significantly increased the content of K, carotene and carbohydrates, but Na and CL percentage was decreased in carrot with bio-fertilizer treatment under saline conditions.

The present study was conducted to evaluate the response of Gladiolus cv. Eurovision plants grown in a sandy calcareous soil to four rates (0, 75, 150 and 300 kg / fed.) of Abou – Tartour rock phosphate (ARP) and four concentrations (0, 2, 4 and 6 g / l.) of active dry yeast (ADY) during 2006 and 2007 seasons.
Different vegetative growth parameters, flowering aspects, corm production and chemical constituents were considerably increased due to the all rates of ARP. Active dry yeast at 4 and 6 g / L. were the most effective treatments for augmenting growth, flowering, corm production and chemical constituents of plant.
So, it could be recommended to supply gladiolus cv. Eurovision plants with the high rate of ARP at 300 kg / fed. and spraying with ADY at 6 g / l. in order to obtain reasonable growth, marketable flowering quality and quantity as well as higher productivity of corms and cormels.
