지벨레린 최아처리가 춘파대맥의 발아생육에 미치는 영향
Effects of Sprouting Treatment with Gibberellin to Germination and the Growth of Spring Barley
초록
춘파과맥
Germination and field test were made with the spring barley sprouted with gibberellin solution of 5 levels from 5 to 100 ppm. Temperatures of room for germination were classified as ordinary and low. Results obtained will be summarized as follows: 1. Sprouting with Gibberellin promoted the germination by two days in ordinary and three days in low temperature without reducing the germination rate. 2. The higher concentration of gibberellin showed the more promotion of growth in early stage. 3. No retardation of root-growth was found by gibberellin sprouting. 4. No promoting effects to germination by gibberellin sprouting was found in field tests. In high concentration, percentage of germination, number of spike and grain yields reduced remarkably. 5. More remarkable tendency of weak growth and longer duration of recovery were found in the higher concentration of gibberellin, but all plots recovered from weak growth at middle stage of plant growth. 6. In gibberellin concentration of 5 to 10 ppm, retardation of germination, weakness of early growth and reducing of spike number were not remarkable while length of spike and 1000 grain weight were increased. Therefore grain yields showed increasing tendency. 7. Promoting the germination may be expected but hastening of heading and maturing may not be available by gibberellin treatment in sprouting.
