    ABSTRACT: Laboratory and greenhouse experiments were conducted to study the role of some vitamins in decrease of seed deterioration of soybean (Glycine max L. Merrill) during storage and enhance seedling vigor. Seeds stored in cotton bags for 0, 2, 4 and 6 month periods after sprayed with Vitamin C (50, 75 and 100 ppm), Vitamin B9 (10, 15 and 20 ppm) and Vitamin A (50, 100 and 150 ppm). Results indicated that nine known genera of fungi were isolated in seed health test, Fusarium followed by Penicillium recorded the superiority in frequency while Rizoctonia came late after Cephalosporium. Vitamins application decrease growth of different fungal genera in all storage periods, moderate level of Vitamin A was more effective. Germination characters (Germination percentage and its energy and index), seedling parameters (shoot length, root depth and seedling dry weight) and seed chemical analysis (oil and protein percentages) were decreased with increasing storage period. In contrast, dead, rotted seeds and rotted seedlings percentage increased significantly with increasing storage periods. Generally, vitamin treatments counteracted the harmful effect of storage on soybean seeds. The application of vitamins as seed treatments increased significantly germination characters, seedling characters and seed chemical analysis as well as survived seed health and minimized dead seeds, rotted seeds and rotted seedlings. Vitamin A was more effective in germination characters while Vitamin B9 was more effective in seedling characters and seeds chemical analysis. The maximum values of shoot length and dry weights of shoot and root were recorded from seed treated with Vitamin A. Moreover, Vitamin C gave the maximum values of chlorophyll a, carotenoids and total phenols. The present investigation recommended using Vitamin A at 100 ppm or Vitamin C at 75 ppm as seed treatment to decrease soybean seed deterioration during storage.

    ABSTRACT: The release of new durum wheat (Triticum durum Desf.) cultivars, concerning genetic and environmental factors, with high yield and quality can be used as a tool to increase the production of durum wheat. Therefore, two field experiments were conducted during successive winter seasons of 2008/2009 and 2009/2010 in poor sandy soil at Researches and Production Station of National Research Centre, Al Nubaria district, Al Behaira Governorate, Egypt in cooperation with Seed Technology Research Department, Agricultural Research Center. Twenty nine genotypes of durum wheat were tested, 28 of them imported from CIMMYT beside local one named ('Beni Sweif 1'). All genotypes were classified to groups according to some central tendency and variation statistical measurements for agronomic characters. More than 86 % from all tested genotypes significantly surpassed on the check variety. The obtained results showed significant differences in all studied characters in the field experiments in both seasons and its combined data. Genotypes No. 15, 5, 3, and 17 recorded the best results in grain yield/spike (1.75-2.03 g) and/fed. (12.87-16.36 ardab); straw yield/fed. (5.53-6.71 ton); biological yield/fed. (7.45-9.16 ton); fertility index (< 97.26%); and they were early heading (> 82 day). The same genotypes recorded moderate results in 1000 grains weight (g); harvest index %; No. of grains/spike; spike length (cm); No. of fertile spikelets/spike; No. of spiklets/spike; No. of leaves/tiller and recorded low leaf blade area (10-15 cm2). It can be recommended by genotypes No. 3, 5, 15, and 17 are promising new genotypes to enter in breeding programmes for durum wheat under Egyptian conditions but need more supplementary investigations i.e. morphological and dissemination, genetic and molecular, agronomic correlation, regression and/or path coefficient, sensitivity to deficiencies of mineral nutrition, stability and adaptability analyses and other parameters which can be describe, classify and select the promising genotype correctly.

    ABSTRACT: In order to reduce the peanut seed deterioration and improve seed quality during storage a laboratory experiments were conducted. Seeds were subjected to different storage periods (0, 2, 4 and 6 months) using biotic (Saccharomyces cerevisiae extract at 25, 50 and 100%) and abiotic (citric and salicylic acids at 10, 15 and 20 mM) agents. After 6 months storage period of the treated seeds the viability of peanut seeds was evaluated under greenhouse conditions. The seed health showed inhibitory effects of biotic and abiotic agents on presence of different fungal genera in all storage periods, Saccharomyces cerevisiae then salicylic acid were most effective. Increasing storage periods from zero to six months significantly decreased germination percentage, germination energy, germination index, seedling length, seedling vigor index, dry weight of 10-seedlings as well as dead and rotted seeds, rotted seedlings and survived healthy seedlings and seed oil, protein and carbohydrates percentages. Treating peanut seeds with 100% Saccharomyces cerevisiae improved germination criteria, seedling characters and seed chemical characters as well as survived seed health and minimized the died seeds%, rotted seeds% and rotted seedlings as compared with the control under all storage periods. Peanut seeds free from aflatoxin B 1 were detected in the moderate and high concentrations of both biotic and abiotic agents. The maximum growth parameter and physiological characters (chlorophylls a and b, carotenoids and total phenols) were recorded from seed treated with 100% Saccharomyces cerevisiae extract after six months storage under greenhouse conditions. It could be recommended to use 100% Saccharomyces cerevisiae extract or 15 mM salicylic acid as seed treatment to improve seed quality and reduce deterioration of peanut seeds under storage.
