种子休眠是指具有生命力的种子,给预适宜的发芽条件而不能发芽的现象。这对抵抗逆境、延续种质具有重要作用。但在种子检验工作中,对休眠种子采用常规发芽试验测定发芽率时,往往难于获得正确结果。为此笔者用了3年时间对我省主要杂交水稻亲本(不育系、保持系、恢复系)和杂交种子进行了试验研
Seed dormancy refers to the seeds of vitality, to the pre-suitable germination conditions and can not germinate phenomenon. This is adversarial adversity, continuation of germplasm has an important role. However, in seed testing, it is often difficult to obtain correct results when the germination rate of dormant seeds is determined by conventional germination tests. For this reason, I spent three years on the main hybrid rice parents (CMS, maintainer and restorer lines) and hybrid seeds in our province
