摘　　要：研究了温度对水稻不育系圣丰1A生育期的影响,结果表明,水稻不育系圣丰1A为感温型品种,其播始历期随日平均温度的升高而降低;圣丰1A有效温度上限值为26℃,日均温度高于26℃时,生长速度随温度升高而降低。Studing on the temperature effect of rice growth stage on CMS line San Feng 1A,the results indicated that rice CMS line San Feng 1A was a thermo-sensitive variety,its duration from seeding to heading was decreased with the rise of daily mean temperature.The effective higher temperature limit of San Feng 1A was 26 ℃.When the average daily temperature was 26 ℃ above,the growth rate decreased with the increase of the temperature.

关 键 词：圣丰1A 播始历期 生长速度
