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 H2O2/Qianglvjing,GA3/Qianglvjing,H2O2,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 dormancy and raise the germination rate of seed.The dormancy from weak to strong is Shuhui 527,Xianghui 299 and Minghui 63.
