| 摘 要： | １９９１年在武昌采用人工光周期处理和自然条件下分期播插等方法，对８６３－１０１－０１专题提供的１１个不育系育性转换的光温反应类型进行了鉴定，初步探明了影响这些不育系育性转换的光温因子和临界光温指标。结果表明，大多数不育系的育性转换均受到光周期与温度的共同作用，纯粹的光敏型或温敏型不育材料是不存在的，从而为选育生态适应性较广的光敏核不育系提供了农业气象依据。

| Abstract: | he types of response to photoperiod and temperature of eleven PGMR lines provided by 863-101m01 of a special subject identified by artificially controlled photoperiods and sowing/transplant under natural conditions in Wuchang in 1991. The photoperiod/temperature factors and their critical indices which affect fertility change of these PGMR were primitively verified. Rusults showed that the fertility change of all the PGMR were controlled by photoperiod and temperature,and the pure PGMR and TGMR materials not exist. Agrometeology basis is provided for seleting and breeding PGMR of ecological adaptability field. |
