Studies on the performances characteristics of collected native sprout soybean Ⅲ. Hypocotyl elongation and relationship between the hypocotyl length and major characteristics

These experiments were conducted to investigate the variability of hypocotyl elongation, and relationship between the hypocotyl length and major chracteristics of collected native sprout soybean. The results obtained are summarized as follows; It follows that it may be reasonable to evaluate the hypocotyl elongation of soybean seeds by comparison of hypocotyl length. And the tested 133 collected native sprout soybean cultivars could be classified as follows. Long; Changsu 1, Wanju 2, Chungeub 1, Buan 4, Gimje 1, Jinan 3. Gurye 1, Sunchon 4, Short; Chonju 7, Chungeub 1, Buan 1, Gurve 3, Jindo 1, Seungju 1, Medium; other 102 cultivars. The rate of hypocotyl elongation was the highest during the hour from 72 to 84 after seeding in paper towel. The large seed produced seedling with longer hypocotyl than did medium and small seed. Hypocotyl elongation by comparison the seed coat color could be classified as follow. Long; emerald green, yellow, naple yellow. Short; amber, moss green, cocoa. Medium; black, cream. As the storage period was long, the hypocotyl length under normal temperature was apparently shortened, but that of seed in refrigerator was not changed.
