摘　　要：首次利用自然光照加人工光照研究了光照长度对萍乡显性核不育水稻育性转换的影响。结果表明:光照长度对萍乡显性核不育水稻育性转换的影响,在可育季节里,萍乡显性核不育水稻的花粉可育率随光长的延长有提高的趋势;在不育季节里,10 h、12 h处理和对照组,育性没有发生转变,但15 h的处理,育性为可育。This paper primarily studied the influence of light length on the fertility alteration of Pingxiang Dominant Genic Male Sterile Rice. The result shows that in fertile season the rate of pollen fertility increases as light length increases, in sterile season this rice was fertile in 15-hour light length while sterile in 10-hour light length, 12-hour light length and CK.
