外源ABA对杂交水稻制种F1穗芽的抑制效应
Effects of Exogenous ABA on Panicle Sprouting of F1 in Hybrid Rice Seed Production
摘要
Abstract
"Panicle sprouting" is one of the major problems in hybrid rice development, there is no an effective technique to solve the problem so far. It was demonstrated by our experiments that panicle sprouting could be effectively inhibited by timely application of exogenous ABA. The results showed that effective concentrations of ABA in this experiment is 75 ml/L and the dosage is 0.38 mg/hill. Exogenous ABA can inhibit panicle sprouting in hybrid rice F1 seed and conventional rice seed production in this experiment condition. These factors as GA3, precipitation during heading time in the seed production field will affect the ABA inhibiting efficiency. It was not found anything negative on F1 germination rate in ABA treatment after a period of storage.关键词
