本试验以4个粳型遗传雄性不育系、8个籼型遗传雄性不育系和一个常规稻作材料,比较研究温度和育性转换的关系,以及它们的细胞生物学特性和生理生化变化。这些材料分别在小穗原基分化到减数分裂期,用人工控制进行短日高温(12h,白天31℃,晚上28℃)或长日低温(14h,白天24℃,晚上20℃)处理。结果如下:1 温度对不育基因表达的影响试验观察表明,安农 s-1、衡农 s-1、1356s、1376s、1402s 和 w7154s 在幼穗发育期间,
In this study, four japonica-type male sterile lines, eight indica-type male sterile lines and one conventional rice were used to study the relationship between temperature and fertility change, as well as their cell biological characteristics and physiological and biochemical changes . These materials were individually differentiated into meiosis during the spikelet primordia and were manually controlled for short day and high temperature (12h, daytime 31 ℃, night 28 ℃) or long day low temperature (14h, daytime 24 ℃, night 20 ℃). The results are as follows: 1 Effects of temperature on the expression of sterile genes The experimental observation showed that during the development of young spikes, Annong s-1, Hengnong s-1, 1356s, 1376s, 1402s and w7154s,
