１９９１～１９９３年对１３个光敏核不育系在早、中、晚三季自然变温条件下进行了６种不同光周期诱导育性转换的试验。结果表明，长日第二光周期对光敏水稻育性转换的诱导效应，决定于其本身的短日第一光周期的感光性强弱。只有感光性强的不育系才表现为光敏，而感光性弱的不育系则表现为温敏。根据对第一光周期的感光性强弱和育性转换的特点。将现有的光（温）敏不育系划分为高温敏型、低温敏型、长日光敏型、近长日光敏型和光温互作型５种类型。当高于育性转换的温度阈值时，光周期控制着光敏不育系的育性表现，温度控制着温敏不育系的表现。不同不育系之间存在育性转换的温度阈值和临界光周期的差异。本文还讨论了两个光周期敏感性的非独立性关系和光（温）敏不育系利用的生态学意义。
From 1991 to 1993, six photoperiod-induced fertility transformations were performed on 13 photoperiod-sensitive genic male sterile lines under natural, early, middle and late three seasons. The results showed that the induction effect of long-day second photoperiod on photo-fertility conversion in rice was determined by the photoperiod of its own short-day first photoperiod. Only the photosensitive male sterile lines showed light sensitivity, whereas the light sensitive male sterile lines showed temperature sensitivity. According to the first photoperiod sensitivity and fertility characteristics of conversion. The existing light (temperature) sensitive sterile line is divided into high temperature sensitive, low temperature sensitive, long-day photosensitive, near long-day photosensitive and light and temperature interaction type 5. Photoperiod controls the fertility of photo-sensitive CMS when the temperature is above the threshold of fertility conversion, and temperature controls the performance of TGMS. Differences in temperature threshold and critical photoperiod between fertility transformations exist among different CMS lines. The paper also discusses the ecological significance of the relationship between two photoperiod-sensitive non-independent relationships and the use of photoperiod-sensitive male sterile lines.
