摘要
温度是诱导Ｗ６１５４Ｓ育性转换的主要因素。在长沙地区不育与可育转换的临界日平均温度为２６．５℃；温度诱导育性转换的敏感期为花粉母细胞减数分裂期。当日平均温度高于２６．５℃时，花粉发育走向败育，表现为不育；在２４℃以下时，多数花粉发育正常，表现为可育；在２４～２６．５℃之间时，部分花粉发育正常，部分花粉走向败育，表现为部分可育。
Temperature is the leading factor inducing fertility transformation of W6154S in Changsha region, the critical daily mean temperature inducing fertility transformation is 26.5℃, and the sensitive period during which temperature induces fertility transformation is meiosis of pollen mother cells. When the daily mean temperature is over 26.5℃, the pollens become abortive and sterility is exhibited. When the daily mean temperature is below 24℃, most of the pollens grow normally. and fertility is exhibited. When the daily mean temperature is between 24℃ and 26.5℃,a part of pollens grow normally and other part of pollens become abortive, and partial fertility is exhibited.
