籼型光敏感核不育水稻在武昌自然光温条件下，具有两个育性转换临界期；其育性表现在受日照长度诱导的同时，温度也起着重要作用；温度对籼型光敏核不育水稻育性影响的敏感期在雌雄蕊原始体形成期至花粉母细胞减数分裂期；温度对花粉育性的影响没有明显的累加效应。
Under the condition of natural light and temperature in Wuchang, indica-type photo-sensitive genic male sterile rice had two critical stages of fertility transition; its fertility performance was induced by sunshine duration and temperature also played an important role; The sensitivities of fertility in paddy during the primordial period from stamen to meiosis of pollen mother cells did not show significant additive effects on pollen fertility.
