| 摘 要： | 对新培育的温敏不育系“417S”进行人工控制条件下的光温处理,研究育性转换的光温反应。研究发现,光照对其育性转换的影响极小,温度是育性转换的主导因子,育性转换的临界发育时期是花粉母细胞形成期至减数分裂期,临界温度是日平均温度23.0 ℃（30.0/20.0）. 同时发现,育性转换的临界温度可能具有上限和下限两个临界值。

| Abstract: | The photo and thermo treatments were conducted on the newly TGMS rice line “90－417s” under the artificial control conditions to study the photo-thermo-responses of fertility change. The results showed that temperature was the main factor for the fertility change and illumination only had the minimum effect on it. The critical growing period of fertility change was from the formation of pollen mother cell to the meiosis, and the critical day-mean temperature was 23.0 ℃(30.0／20.0). Furthermore, that temperature probably had an upper limit value and a lower limit value. |
