For this study, Superior Seedless grapevines (<em>Vitis vinifera</em>, L.) were used as source of scions and four rootstocks, Teleki 5C, Paulsen 1103 and SO4 (American stocks) besides of the control (own-rooted). The following determinations were carried out : bud behaviour, average leaf area, yield per vine, physical and chemical characteristics of bunch and berries. The data reveal that, most of rootstocks increased N, P, K contents in the leaves and total carbohydrates in the canes. The results also showed that bud burst, bud fertility and leaf area of Superior seedless grapevine on Telelki 5C rootstock gave a higher value than the other rootstocks or the control. Superior on Teleki 5C rootstock increased the yield per vine, cluster weight and number of berries per cluster as compared with the other rootstock or the control. Vines grafted on Paulsen 1103 or Teleki 5C increased berry weight, size and juice volume compared to other treatments used. Whereas, the control gave the lowest values in this respect. Superior own rooted (control) generally resulted a higher percentages of SSC, SSC/acid ratio and lower acidity in berry juice than the other rootstocks used. The highest value of carbohydrate in canes was observed in the vines rooted on Teleki 5C, Paulsen 1103 or SO4 than the control. Whereas, N content in the leaves of Superior in own rooted was higher than other rootstocks used. Furthermore, the content of P in leaves of Superior on SO4 and Paulsen 1103 rootstocks were higher than the other Teleki 5C rootstock or the control. Whereas, there is no significant differences in potassium content in leaves between the rootstocks used or the control.https://jpp.journals.ekb.eg/article_119177_f977b6de8f964fb00abb7961dc424648.pdfMansoura University, Faculty of AgricultureJournal of Plant Production2090-3669341220091201EFFECT OF COLD STORAGE AND DIFFERENT PACKAGING MATERIALS ON THE QUALITY OF FRESH ROSEMARY HERB: I- EFFECTS ON MARKETING VISUAL QUALITY AND SHELF-LIFE112171123111917810.21608/jpp.2009.119178ENH.

Some herbs are sold fresh rather than dry because they do not retain their flavor when dried. Rosemary (<em>Rosmarinus officinalis</em>, L.) plant is an important aromatic culinary herb.
A study was carried out during two successive summer seasons 2006 and 2007, at the Post Harvest Lab in the Veget. and Flor. Dept., Fac. of Agric., Monsoura Univ. Fresh rosemary herbs were packaged in nine different packaging materials: Butter bags (P1), Cellophane bags (P2), Nylon bags (P3), Polyethylene bags (P4), Aluminum foils (P5), Aluminum plates covered with foil (P6), Aluminum plates covered with plastic film (P7), Foam plates covered with foil (P8), Foam plates covered with plastic film (P9). The packages were stored at (room atmosphere, 1, 3, and 5 °C) for 6 weeks.
This study was conducted to study the effect of cold storage and different packaging materials on the quality of rosemary fresh herb.
This part (I): aimed to investigate the effect of cold storage temperatures and different packaging materials on the marketing visual quality and shelf life of fresh rosemary herb.
The results showed that increasing storage period resulted in increasing of the fresh weight loss and decreasing the total chlorophyll content. While, the shortest storage period of the herb, the less the changes in their fresh weight, and the slowest the chlorophyll degradation.
Herbs kept in Butter bags (P1) lost their fresh weight faster and sharper than those kept in other packaging materials, while those in Aluminum foils (P5) were the least to lose weight and had steadier pattern than the other packaging materials. Herbs kept in Butter bags (P1) and Foam plates covered with plastic film (P9) had lower chlorophyll content than other packages.
At the end of the storage period (after six weeks), herbs kept in Aluminum foils (P5) and Aluminum plates covered with foil (P6) had the least fresh weight loss percentage, and the highest chlorophyll content in both seasons. It is also clear that Aluminum foils (P5) and Aluminum plates covered with foil (P6) kept the chlorophyll content of the herb at high values for long period especially at 1°C.
The shelf life of the three storage temperatures varied slightly among each other’s but significantly with room temperature, with favor to the lower cold temperature. The worst package was Butter bags (P1) in both summer seasons. Aluminum foils (P5), Aluminum plates covered with foil (P6), and Foam plates covered with foil (P8) had longer shelf life than other packaging materials.
Summing up all factors, herbs in Aluminum foils (P5) and Aluminum plates covered with foil (P6) storedat 3 °C maintained their fresh weight, chlorophyll content, and achieved longer shelf-life than other treatments in both seasons.https://jpp.journals.ekb.eg/article_119178_557df3f489cd8aafb0d79f5c8c2f3da6.pdfMansoura University, Faculty of AgricultureJournal of Plant Production2090-3669341220091201EFFECT OF COLD STORAGE AND DIFFERENT PACKAGING MATERIALS ON THE QUALITY OF FRESH ROSEMARY HERB: II- EFFECT ON THE ESSENTIAL OIL PERCENTAGE AND COMPOSITION.112331124511917910.21608/jpp.2009.119179ENH.

Some herbs are sold fresh rather than dry because they do not retain their flavor when dried. Rosemary (<em>Rosmarinus officinalis</em> L.) plant is an important aromatic culinary herb. Essential oil of rosemary is considered one of the strongest natural antioxidants. A study was carried out during two successive summer seasons 2006 and 2007, at the Post Harvest Lab in the Vegt. and Floric. Dept., Fac. of Agric., MonsouraUniv.
This part (II) aimed to investigate the effect of cold storage temperatures and different packaging materials on the essential oil percentage and composition of fresh rosemary herb and the changes that took place during storage until the end of their shelf life as fresh herbs. Fresh rosemary herbs were packaged in nine different packaging materials: Butter bags (P1), Cellophane bags (P2), Nylon bags (P3), Polyethylene bags (P4), Aluminum foils (P5), Aluminum plates covered with foil (P6), Aluminum plates covered with plastic film (P7), Foam plates covered with foil (P8), Foam plates covered with plastic film (P9), and then stored at (1, 3, and 5 °C) for 6 weeks. Gas Liquid Chromatography (G.L.C.) analysis was carried out in second season summer 2007 to compare between the composition of the oil of the freshly harvested herb and the of oil of herbs packaged in Aluminum plates covered with foil (the package that gave best marketability for fresh herb shown in Part 1) after one and three weeks of storage under the three cold storage temperatures.
The results showed that the essential oil percentage of the herb increased with increasing the length of the storage period. Oil percentage in herbs stored at 3 °C was superior to those stored under the other two temperatures in both seasons. Herbs kept in Butter bags (P1) had maximum oil percentage until the second week of storage. Cellophane bags (P2) were the highest in the fourth week of storage, while at the fifth week of storage; Foam plates covered with foil (P8) was the highest. At the end of six weeks of storage at 3 ͦ C only Aluminum plates covered with foil (P6) and Aluminum foils (P5) were marketable in both seasons, but (P6) had higher oil percentage than (P5).
GLC analysis identified 14 compounds constituted 88.8 % of the essential oil of rosemary fresh herb after harvest (control). The identified compounds included seven hydrocarbons forming 57.25 % and seven oxygenated forming 31.55 % of the total compounds. Hydrocarbons were α- pinene (11.93 %), β- pinene (7.01 %), limonene (3.01 %), ρ- cymene (10.11%), camphene (7.94 %), γ- terpinene (9.23 %), and α- terpinolene (8.02 %). Oxygenated compounds were 1,8 cineole (7.27 %), linalool (6.79 %), verbenol (1.94 %), borneol (3.83 %), thymol (4.47 %), camphor (2.3 %), and terpineol (4.95 %). The total percentage of hydrocarbons and oxygenated compounds decreased after storage compared with the control. The total percentage of each of hydrocarbons and oxygenated compounds were higher at 3°C than those at either 1 or 5 °C at the two comparable storage periods. At a storage temperature of 3°C, all hydrocarbons had higher percentages after one week of storage than after three weeks of storage, except for β-pinene and limonene, while all oxygenated compounds had higher percentages after three weeks of storage than after one week of storage, except for thymol and terpineol.

The results revealed that prolong irrigation intervals and storage period reduced germinability (as measured by germination percentage, germination after aging, first count, germination index, germination energy and germination rate) and seedling vigor (seedling length, seedling dry weight and its vigor index), meanwhile, increased mean germination time. Increasing potassium fertilizer rates improved seed viability and seedling vigor traits, on the contrast, decreased mean germination time. High significant effect for the interaction between storage period x irrigation intervals, storage periods x potassium fertilizer rates and irrigation intervals x potassium fertilizer rates were obtained for all studied traits.
The results suggested that sowing grain sorghum (c.v.

Ascorbic acid content in two main parts (stem and calyx end of fruit) and three sub-main parts (peels, inner and outer pulps) of the fruits were measured. Internal browning in mango fruits found to be dependant on the fruit AA content. Exogenous application of AA (5.6 mM) decreased IB incidence when the fruits immersed for 24 hour compared to these immersed in water for the same time and stored at ambient conditions for 35 days. Mango fruits pre-storage immersing in diluted AA (5.6 mM), water is absorbed throughout the peel cells causing an increase on AA content and a decrease on its concentration. The decrease of IB incidence was appeared due to such increase on AA content in inner and outer parts of the fruit. This protection of the treated fruits may be related to the consumption of the externally added AA. Therefore, it could be said that the application of AA increases mango fruit quality, through protecting the from development of IB, also, the obtained results indicated that such treatment maintain the total phenols (TP) content in fruits during cold storage constant.https://jpp.journals.ekb.eg/article_119187_21871638d39695bb6df3f5fc23addf27.pdfMansoura University, Faculty of AgricultureJournal of Plant Production2090-3669341220091201EFFECT OF PLANTING DATES AND SEED SIZE ON PRODUCTIVITY AND QUALITY OF SOME FABA BEAN CULTIVARS113111132511918910.21608/jpp.2009.119189ENA.

<strong>The main results could be summarized as follows:</strong>
1- Planting faba bean in the intermediate date (10<sup>th</sup> November) produced the highest values of seed yield and its components and also high seed quality traits ranked by early (20<sup>th</sup> October) then late planting dates (1<sup>st</sup> December).
2- Sakha 1 cultivar ranked first whereas Giza 843 and Masr 1 were ranked second and third, respectively in all studied characters.
3- The effect of seed size on seed yield and its components and seed quality characters was significant, except for the number of seeds/plant, pod weight, number of seeds/pod and dry weight of seedlings in the second season only. Large size of sown seeds recorded the highest values of all studied characters, followed by medium then small size. There were insignificant differences between large or medium size of seed in some yield component and seed quality as well as seed yield/fed.

Two of the most commonly used herbs and cultivated throughout the Mediterranean region are parsley (<em>Petroselinum sativum</em> Hoffm.) and dill (<em>Anethum graveloens</em> L.) plants belongs to Fam. "Apiaceae" (Umbelliferae) were used in the present work.
The present study was carried out at the Experiment Farm of Horticulture Research Station in EL-Kassasen, Ismailia Governorate, Egypt, in two successive winter seasons of 2006/2007 and 2007/2008 to investigate the influence of some drying methods (shade at 20 ±2 °C, oven at 45 °C, sun at 30 ±3 °C and greenhouse at 35 ±5 °C), on the plant dry weight (g / 100g FW), moisture content (%), the volatile oil quality and quantities of parsley and dill plants.
The physical and chemical properties of the volatile oil of the two fresh plants viz., specificgravity, refractive index and optical rotation were determined and are included in this study.
The results showed that the shade drying method was the best treatment to produce the highest volatile oils percentage of both plants, while oven drying gave the highest percentage of volatile oils components. On the other hand, sun drying method was the lowest one since it caused a decrease in the plant quality.
The G.L.C. of the parsley volatile oil revealed a total of 10 compounds were α- and β- pinene, sabinene, limonene, α- and β- phellandren, myrcene, p-cymene, myresticine and apiol. The total identified compounds constituent 74.6, 79.5, 91.1, 86.6 and 72.1 % in the oil of the control, shade, oven, sun and greenhouse drying methods, respectively. While, the G.L.C. of the dill volatile oil revealed a total of 11 compounds were α- and β- pinene, myrcene, limonene, p-cymen, α- and β-phellandren, 3,9- epoxy-p-menthlen, trans - dihydrocarvon, cis- dihydrocarvon and carvon. The total identified compounds constituent 100, 97.7, 98.2, 92.2 and 89.4 % in the oil of the control, shade, oven, sun and greenhouse drying methods, respectively. The method of drying affected the proportion of the oil components in the two plants.
The volatile oil % of the total main components (α- and β- pinene, myresticine and apiol) was 34.5, 46.7, 59.4, 45.8 and 36.8 % of parsley plants in the oil of the control, shade, oven, sun and greenhouse drying methods, respectively. While, the volatile oil % of the total main components (α- phellendren and limonene) was 71.2, 71.5, 78.6, 57.9 and 64.8 % of dill plants, in the oil of the control, shade, oven, sun and greenhouse drying methods, respectively.
The method of drying included oven dried at 45 °C for 6 hr. was the best procedure to produce parsley and dill dried materials if compared with the other tested methods, since it kept the leaf volatile oils with characterised features increasing yield quantity and quality.

Dept., Fac. of Agric., Ain Shams Univ., Cairo, EgyptJournal Article20201017This study was carried out at the Barrage Horticulture Research Station, Qaluobia Governorate, and the StrawberryImprovementCenter, Faculty of Agric., Ain Shams Univ. during the period from 2005 to 2009. The aim of this study was to produce and selected some local promising strawberry hybrids from the commercial cultivars through the traditional crossing method. Four potential cultivars i.e., Sweet Charlie, Diamonte, Camarosa and Vantana were used in the crossing and six hybrids were chosen and evaluated in the nursery stage and also for yield and fruit quality in two seasons. The study aimed also to determine the average degree of heterosis (ADH) regarding some horticultural characters viz., yield component, and fruit physical and chemical characteristic for the obtained hybrids. This knowledge about this sort of genetics would be helpful to the plant breeder for planning a successful breeding program. Results revealed that hybrid K102 (Kanater 102) exhibited the highest values in total yield, average fruit weight, fruit firmness and total soluble solids content as compared with its parents suggesting hybrid vigor for these traits. Hybrid K101 showed the highest values of average fruit weight, total soluble solids, ascorbic acid content and the lowest total acidity as compared with the parents. Also, K105 gave the highest values of number of fresh and dormant transplants and the lowest values of total acidity. Results indicate also that K 106 showed the highest values of total plant yield and average fruit weight as compared with the parental cultivars. Hybrids, K103 and K107 showed the highest values in fruit firmness and average fruit weight respectively as compared with the parents. Also, Sweet Charlie and Camarosa parents were the highest in early yield per plant and average fruit weight respectively. In general, the results on heterosis showed that most produced hybrids exhibited higher values than the better parent concerning most studied traits. The observed hybrid vigor for these traits encourages the production of F<sub>1</sub> hybrids in strawberry for commercial production.
The study concludes that six new local strawberry hybrids have been produced with high productivity and desirable eating quality than their parents.https://jpp.journals.ekb.eg/article_119193_1ed958597d8363634017c37ef5004448.pdfMansoura University, Faculty of AgricultureJournal of Plant Production2090-3669341220091201EFFECT OF BIOSTIMULANTS REMIDIATION SUBSTANCES (BRS) ON SEED GERMINATION AND SEEDLING GROWTH OF SOME SUGAR BEET CULTIVARS UNDER STRESS CONDITIONS113551137311919610.21608/jpp.2009.119196ENM.

Analysis of variance showed a significant effects of Mannitol level and/or the BRS used (P<0.001)on the rate of germination as well as fresh and dry weights of the seedling. The reduction in germination % and the increase in time required for seeds to germinate due to stress was observed in both sugar beet cv(s) studied. However, cv(2) was more susibtable than cv(1) in this respect.
Germination was progressively inhibited by an increase in mannitol level in both cv(s). The strongest inhibition occurred at the third mannitol level (0.3 M) in cv(2). However, cv(1) did not exert any significant effect on ultimate germination % under the 2<span style="text-decoration: underline;"><sup>nd</sup></span> mannitol level. Increasing mannitol level was associated with a marked reduction in AsA, glutathione; GSH, catalase;CAT, guaiacol peroxidase;GPOD and superoxide dismutase;SOD as well as total carbohydrates and total N concentrations, whereas, increased that of H<sub>2</sub>O<sub>2</sub> and proline as well as T.S.S. and osmotic pressure of the leaves and roots in both seedling cv(s) .
BRS decreased concentrations of H<sub>2</sub>O<sub>2</sub> and proline whereas, increased that of AsA and GSH as well as CAT, GPOD and SOD in the development seedling of both cv (s). Treatment with SWE showed an additive effects to that of stress treatments on increasing non-enzymatic and enzymatic antioxidants concentrations in both cv (s). Cv (1) showed, in general higher concentrations of AsA and GSH as well as CAT, GPOD and SOD than that of cv (2) .
The interactions treatments showed that any of the BRS used elevating the harmful effect drought stress caused by increasing mannitol level up to 3<span style="text-decoration: underline;"><sup>rd</sup></span> one (3.0 M) .

The aim of the first experiment, was to study the effect of harvesting dates 45, 55, 65 and 75 days from 50% heading under three wheat seed classes (foundation, registered and certified) on yield and its components (c.v. Giza168). The second experiment was conducted at the laboratory of Seed Technology Research Unit, El-Mansoura, Dakahlia Governorate and aimed to study the effect of harvesting dates and wheat seed classes seed quality during different storage periods, i.e. (0, 3 and 6 months after harvesting).
The results revealed that, harvesting dates had significant effects on grains moisture content, number of spikes/m<sup>2</sup>, spike weight, number of spikeletes/ spike, number of grains/spike, grains spike weight, 1000-grain weight and grain yield. Harvesting wheat plants after 65 day from 50% heading produced the highest means yield and its components traits i.e. (spikes number/m<sup>2</sup>, 1000-seed weight, grain yield) in both seasons. Result showed that insignificant differences among seed classes on growth characters, yield and its components. In general, number of spike/m<sup>2</sup>, spike length, number of spikeletes/spike, number of grain/spike and grain yield were recorded maximum value from foundation seed followed by registered and certified seed category.
Increasing storage periods had significant effect on all the studied traits. While the prolong the storage periods from 0 to 6 months from storage lead to the decrease in germination percentage, speed of germination, germination energy and germination rate and the decrease in seedling vigor traits (seedling length and fresh and dry weight) and carbohydrate percentage in the both seasons. While this increase in storage period lead to the increase in mean germination time, protein content, insect infection percentage and seed dry weight loss percentage in the first and second seasons. Harvesting dates significantly affected on germination energy, germination rate, seedling fresh weight, seedling dry weight, insect infection percentage, seed dry weight loss, protein content and carbohydrate percentage in the first and second seasons. While it had different effects on speed of germination only in the first season.
The interaction among storage periods, harvesting date and seed classes had a significant effect on germination energy and seedling fresh weight in the first and second seasons and seedling dry weight in the first season only.https://jpp.journals.ekb.eg/article_119198_bd775550c751997ab1d5e8d33c8aaa20.pdf
