Role of Some Vitamins in Decreasing of Soybean Seed Deterioration During Storage

M.A. El-Metwally, Aml E.A. El-Saidy and K.M. Abd El-Hai

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 decreased 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 length 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.
