水稻의 穗發芽에 關한 硏究 (Ⅰ) 收穫 및 置床時期의 影響 = Studies on the Viviparous Germination in Rice Ⅰ.Effects of Harvesting and Seeding time

다국어 초록 (Multilingual Abstract)

This study was conducted in 1986 to investigate the vivaparous germination in rice. Two varieties, Daeseongbyeo and Chilseongbyeo, were transplanted on May 25 and June 5 and panicles were harvested 5 times with the interval of 5 days beginning 30 days after heading. Panicles were seeded in incubator at 20℃ right after harvest and after drying and storage to observe the germination. Rate of viviparous germination of Daeseongbyeo was higher than that of Chilseongbyeo regardless of the seeding time. Rate of vivaparous germination of May 25 transplanting was higher than that of June 5 transplanting. Germination of Daeseongbyeo was not afftected by seeding time. Viviparous germination rate of Daeseongbyeo appeared to be increased as the harvesting was posponded. On the other hand, Chilseongbyeo did'nt germinate when seeded right after harvesting and rate of vivaparous germination was decreased as the harvesting was postponded. Vivaparous germination was higher in the order of top > middle > bottom part on a panicle, while grains on the primary branches showed higher vivaparous germination than those on the secondary branches.
