摘要
通过在不同生态点的育性试验 ,观察光敏小麦雄性不育系A31的育性表现和育性转换特性。A31在 7个不同生态点的自交结实率结合各试验点的光温条件分析表明 ,其雄性育性随日长增加有明显的下降趋势 ,日长是影响A31育性的主导因素 ,在日长相近条件下 ,温度对A31育性也有一定的效应 ;A31育性转换的临界日长约在 14
Through observing fertile changes of A31 by the fertility experiments in 7 different ecological areas. the result showed that the male fertility of A31 will decline when the day length becomes shorter. The day length is the majorcause of fertile changes of A31.The male fertility of A31 is also sensitive to the temperature. The critical day-length of fertile changes of A31 is about 14.5 hours.
