药剂浸种解除3个水稻恢复系休眠性研究
|
摘要
采用双氧水/强氯精、赤霉素/强氯精、双氧水、强氯精、赤霉素等药剂对处于休眠期的3个水稻恢复系进行浸种处理,研究各药剂对种子萌发的影响,以探讨恢复系休眠特性及解除方法。结果表明,各药剂处理都能不同程度的解除种子的休眠,提高种子发芽率。3个恢复系中蜀恢527的休眠性最弱,湘恢299次之,明恢63最强。
In order to explore the dormancy characteristics of restorer line and the method of breaking dormancy,the germination rate of seeds after soaking with H2 O2/Qianglvjing, GA3/Qianglvjing, H2 O2, Qianglvjing and GA3 were compared in this experiment,using Shuhui 527, Xianghui 299 and Minghui 63 as materials. The results indicated that different regents treatments could break seed dor-mancy and raise the germination rate of seed. The dormancy from weak to strong is Shuhui 527, Xianghui 299 and Minghui 63.
