摘要/Abstract

摘要： 采用盆栽方式，通过人为疏枝减库平衡库源关系，研究短日低温、高温，长日低温、高温条件下不同温敏型两系杂交稻F1育性(受精率)的变化。结果表明：1，低温敏型F1育性稳定，不论长日或短日都对温度变化表现钝感。高温敏型及反向温敏型F1育性对温度的反应与其母本基本一致；2,温度高低不是影响不同温敏型F1育性变化的唯一因子

Abstract: The F1 fertility rate (FR) of lower-，higher-，and negative- thermo-sensitivity (LTS，HTS & NTS) hybrid rice was investigated under different temperature & light conditions. The results showed：1.The F1 FR was relatively stable for LT hybrid rice while the others were not stable；2.Temperature was n

Key words: F1 fertility rate(FR), TGMS hybrid rice, Temperature & light response.
