摘要
采用分期播种的方法,在云南省水富县300 m,700 m两个海拔试点上,对8份水稻光温敏核不育材料的育性表现情况进行观察。结果表明:不同材料间的育性表达随光温变化呈现出多样性;同一核不育系的育性一般均随海拔的升高而降低,随播期的延迟而升高。并对材料的温敏时期作了分析。
By seeding on different dates,growing at natural condition of 300 m and 700 m vertical elevation in Shuifu county, Yunnan province, the effect of ecological environment on the fertility of PTGMS lines was studied. The result indicated that the fertility of different materials took on various change as the daylight and temperature changed from short and low to long and high; The same PTGMS line＇s fertility gone down with the altitude＇s increasing in common, up with the delay of seeding date. The temperature-sensitive period was also studied in this paper.
