在网室和温室两种条件下观察了高温对水稻细胞质雄性不育系育性表达的影响。发现不育系在其幼穗分化阶段受到持续高温作用后,花粉育性会发生不育→可育的转变,并能部分自交结实,在一定的范围内,温度越高,持续的时间越长,不育系产生的可育花粉就越多。恢复了的可育性能够传递。
The effects of high temperature on the fertility of cytoplasmic male sterility (CMS) lines in rice and greenhouse were observed. It was found that the sterile line could undergo sterile and fertile transformation after being continuously exposed to high temperature during its panicle differentiation stage and could partially self-pollinate. Within a certain range, the higher the temperature and the longer the duration Long, sterile lines produce fertile pollen more. Restored fertility can be passed on.
