| 摘 要： | 本试验通过在广州对宜D1S的周年育性观察及人工短日处理对其育性转换的影响分析得到：(1)宜D1S是一个光敏性较强的材料，在广州一年中具有明显的从不育→可育→不育的育性转换特点。(2)宜D1S的光敏期为幼穗分化Ⅰ期～Ⅲ期。在常温下光敏期适当的短日处理可使育性趋于完全不育，但在高温下光敏期短日不育效应被削弱。作者认为

| Abstract: | Fertility alteration in a year of YiDls was observed in Guangzhou, in addition, effect of artificial short photoperiod treatment on fertility alteration in YiDls was analyzed. The results showed: (1) YiDls expressed stronger photoperiod sensitive sterility. In Guangzhou, the characteristic of fertil |
