摘要
研究了不同pH碱液浸种对水稻种子发芽的影响。结果表明:在供试的水稻品种中,不同pH条件对水稻种子发芽影响变化趋势一致,其发芽势、发芽率均随pH的升高和碱液胁迫强度时间的延长而降低,异形芽率则升高,在pH超过9时,水稻种子发芽势、发芽率为0,5个品种中牡丹江27和松粳12抗碱性能力稍强。
The effect of different pH of the lye soaked rice seed on germination of rice was studied. The results showed that different pH conditions on the impact of changes on rice seed germination indicated the same trend in the tested rice varie ties,its germination potential and the germination rate both decreased with the pH increasing and the extension of time stress strength,and the profiled bud rate increase. Rice seed germination potential and the germination rate were 0 when pH was more than 9. In the five text varieties,Mudanjiang 27 and Songjing 12 were more resistant to lye.
