Tow field experiments were conducted at Tag El-Eiz Experiment Station, AgricultureResearchCenter during2005/2006 and 2006/2007 seasons, while storage studies and viability tests were conducted at Giza seed Technology Lab. under common conditions from June 2006 till December 2008. The aim of this study was to investigate the effect of three harvesting dates i.e, 60, 70 and 80 days after 50% heading and four storage periods i. e. 0, 6, 12 and 18 months on wheat seed quality. The results revealed that early harvesting (60 days after 50% heading) reduced seed germinablity under optimal and stress conditions, seedling vigor and seed electrical conductivity. Meanwhile, seed harvested after 70 and 80 days after 50% heading had high viability so that the differences in quality measurements were insignificant. The results revealed also that prolonging storage periods cause deterioration in seed quality and it was more obvious in earlier harvested seeds and those had high moisture content. Moreover, the variation in seed moisture content at harvesting time and during storage was related with the degree of seed deterioration. A combination of quality traits or lab. Testes are more useful than evaluation of one trait by single test. The results suggested harvesting wheat seeds (c.v. Giza 168) after 70 days from mentoring 50% heading or with about 14 % moisture content and storage for 12 month under open-air storage in order to have seed germination above the standard of wheat certified seed (85%).Mansoura University, Faculty of AgricultureJournal of Plant Production2090-36691120100101HETEROSIS AND COMBINING ABILITY IN GRAIN SORGHUM UNDER SALINE CONDITION39548606410.21608/jpp.2010.86064ENA.

Parents and hybrids were evaluated in field traits in 2004 at Ras Sudr, South Sinai , Egypt under two irrigation water salinity levels i.e. 4000 and 7000 ppm. Mean squares due to parents were significant for all studied traits characters under both salinity levels. Data indicated that heterosis related to the better parents was manifested for all studied traits. The highest positive and significant heterosis for grain yield was 10.40% (ICBA-4 × ICBA-3) under 4000 ppm. However, -3,28 % (Dorado × ICBA-4) was the highest negative heterosis under 7000 ppm. ICBA-2 and ICBA-3 as well as the local variety Dorado had the highest positive and significant GCA effects for all the studied characters under low and high salinity levels. ICBA-1 × ICBA-2 was earliest for 50% heading under low salinity level. While, ICBA-5 × ICBA-4 was the best SCA effects under high salinity levels. ICBA-3 × ICBA-1 had the shortest plant SCA effects under low salinity 4000 ppm. However, ICBA-2 × ICBA-4 was preferred plant height SCA effects under high level 7000 ppm. Dorado × ICBA-5 had the tallest panicle length SCA effect under both salinity levels. Dorado × ICBA-3 was largest panicle width SCA effect under 4000 ppm. While, ICBA-5 × ICBA-4 was the best panicle width under 7000 ppm . Dorado × ICBA-4 and ICBA-3 were the heaviest grain weight for SCA effects under both salinity levels. However, ICBA-5 × ICBA-4 and Dorado × ICBA-4 were best crosses for grain yield/ plant SCA effects under 4000 and 7000 ppm respectively. SCA variance was more important than that of GCA for grain yield and its components.
The hybrids (ICBA-5 × ICBA-4) and the reciprocal ( Dorado × ICBA-4 ) out yielded other tested hybrids under different environments and thus we recommend further testing of this hybrids in the evaluation traits in order to release. It was improved the commercial sorghum hybrids under saline condition and it use sorghum genotypes ICBA-3, 4 and ICBA-5 with the local variety i.e. Dorado.Mansoura University, Faculty of AgricultureJournal of Plant Production2090-36691120100101EFFECT OF DODDER AND SOME CONTROL METHODS FOR PRODUCTIVITY OF EGYPTIAN CLOVER CULTIVARS55658606510.21608/jpp.2010.86065ENA.

The obtained results revealed that most of the applied concentrations of ascorbic acid (200, 400 and 600 ppm) promoted significantly the investigated morphological characters (plant height, number of leaves/plant, total leaf area/plant, fresh weight of shoot/plant and dry weight of shoot/plant) of vegetative growth of African Mahogany (10 months old) and produced vigorous transplants in both studied seasons. The maximum promotion was achieved at 600 ppm ascorbic acid which in turn being statistically indifferent with the effect obtained by 400 ppm ascorbic acid in this concern. Likewise, the maximum significant increase in concentration of photosynthetic pigments (chlorophyll a, chlorophyll b and carotenoids) and of total sugars in leaves of African Mahogany plant aged 10 months was detected at 600 ppm ascorbic acid. Also, such treatment caused considerable thickness of the main stem of African Mahogany plant aged eight months by increasing thickness of both phloem and xylem tissues as well as by increasing diameter of pith. Likewise, average diameter of vessel was increased in treated plants to cope with vigorous growth induced by foliar application with 600 ppm ascorbic acid.Mansoura University, Faculty of AgricultureJournal of Plant Production2090-36691120100101YIELD AND NUTRIENT UPTAKE OF SOME FABA BEAN VARIETIES GROWN IN NEWLY CULTIVATED SOIL AS AFFECTED BY FOLIAR APPLICATION OF HUMIC ACID77858606710.21608/jpp.2010.86067ENM.

There were significant differences between treatments and control for seed yield, biological yield and harvest index. The reaction between the treatments and the varieties showed that foliar application of humic acid for Giza-461 at concentration of 20 cm/l enhanced the number and weight of pods and straw as well as seed, biological yield. All treatments of humic increased the nutrient uptake more than control. The highest N uptake was attained with 20cm/l and the highest Fe and Mn uptake was with 5 cm/l. The highest uptake of nutrients as affected by humic foliar application was obtained from 20 cm/L with Giza-461, from 5 cm/L with Giza-3 and 10 cm/L with Giza-429. It seems that foliar application of humic acid under such conditions is more effective in improving seed nutrient uptake and yield of faba bean varieties under study.Mansoura University, Faculty of AgricultureJournal of Plant Production2090-36691120100101EFFECT OF PLANT EXTRACTS ON SEED QUALITY OF SOME FORAGE CROPS DURING STORAGE87998606810.21608/jpp.2010.86068ENAbeer El- Ward A.IbrahimSeed Tech.

Laboratory experiment was carried out at Mansoura Seed Technology Research Unit, Seed Technology Research Section, Field Crops Research Institute, Agricultural Research Center, Egypt during 2008 and 2009 years to evaluate bioassay effects of (Ramith and Oshar) cholorophorm and ethanol extracts on <em>Bruchidius trifolii (Poc),</em> and the effect of treating seed of Egyptian Clover (<em>Trifolium alexandrinum L.)</em> c.v. helaly, Alfalfa (<em>Medicago sativa L.</em>) c.v. Ismaelia 1 and Fahl berseem with these plant extracts on seed quality and insect infestation during different storage periods (0, 6, 12 and 18 months). The results revealed that Ramith cholorophorm and Oshar ethanol extracts were the most toxic for (Bruchidius trifolii) followed by Oshar cholorophorm and Ramith ethanol extracts and the values of Lc50 were (4753.9, 8514.3, 11026.9 and 20649.6 ppm), respectively. After six months from storage, the germination percentage for both of Alfalfa, Egyptian clover and Fahl berseem seeds pass the minimum level for the acceptance of certified seed (85%). Insect inspection cleared, the insect infestation level in Alfalfa seed (4.45%) was the less , followed by both of Egyptian clover and Fahl berseem (6.4 and 6.2%). Treated seed with Ramith cholorophorm extract, produced high germination percentage, seedlings vigour and the lowest level of insect infestation (3.75%) comparing with untreated seed while its germination percentage reduced less than the acceptance level for certified seed and the insect infestation level increased to (8.67%). After storage with 18 months, germination percentage reduced gradually and becomes less than the acceptance level for certified seed and Alfalfa was the less in reduction of seed germination and seedling vigour traits. In general, comparing with the previous storage periods, seed quality decreased and insect infestation increased and reached to 22.67 % for untreated seed. Storage periods negatively and significantly correlated with both of germination %, accelerated aging germination % and seedlings vigour index and highly positively correlated with insect infestation % and electrical conductivity. Also, insect infestation % negatively and highly correlated with germination % and seed lings vigour index.
This study suggested, using seed protectants such as Ramith cholorophorm and Oshar ethanol extracts for protect Alfalfa, Egyptian clover and Fahl berseem seed against Bruchidius trifolii (Poc). Also, planting (Alfalfa, Egyptian clover and Fahl berseem) certified seed in the same production year is preferable well but Clover carry over seed should be stored at optimum conditions and when planting seed rate should be increased to redress the reduction in seed quality.Mansoura University, Faculty of AgricultureJournal of Plant Production2090-36691120100101EEFECT OF SOME APPLIED ANTIOXIDANTS ON PHYTOHORMONES CONTENT OF TWO RICE (Oryza sativa L.)

Besides, vegetative growth parameters , shoot length and thickness, number of leaves per shoot and number of internodes per shoot were promoted.
The experiment led to the conclusion that fruit thinning of olive with ethrel at 300 ppm or NAA at 150 ppm in on-years of biennial bearing cycle reduce alternate bearing severity and improved fruit quality in both "On" and "Off" years
