摘要
本文依据两系杂交水稻不育系育性转换的临界日长、临界温度和出现生理不育的低温界限为指标,初步分析了海南岛南、中、北部一年中大于95%的气候保证率,短于临界日长、低于可育上限温度并高于可育下限温度的持续时间,以说明两系杂交水稻不育系在海南繁殖的气候适应性。
Based on the theory of the transformation of the sterile rice when it meets a day length longer than the critical day length or the temperature higher than the critical temperature, and the theory of physical sterility of rice when it meets critical low temperature, The author analyzed the climatic adaptability of rice with a Light (or Temperature) Sensitive in Hainan. The study was based on the analysis of the probability (higher then 95%) of the weather that could meet the requirement of the critical day - length, and the proper temperature between the critical low temperature and critical high temperature in southern, central and northern part of Hainan.
