Growth of Soybean Sprouts Affected by Period and Method of Seed Storage

Germination of soybean and growth of its sprouts should be affected by storage condition and period of seeds. The experiment was conducted to examine the effects of period stored at cold room and storage conditions on their growth and morphological characters. The seeds, cv. Pungsannamulkong, were stored at for 1 or 2 years, and by the three different storage methods of indoor, cold room, or transfer of indoor to cold room. Compared to the seeds stored for 2 years, one-year seeds had higher rate in hypocotyl of longer than 7 cm, root and hypocotyl lengths, and more hypocotyl fresh weight although there was not significant difference in total fresh weight. In the storage method experiment, one-year seeds stored at cold room and by transfer of indoor to cold room showed better growth, more lateral roots and fresh weights, although only two-year seeds stored at cold room did the same response, indicating that growth of soybean was affected by period and method of seed storage.
