摘要
对８个水稻品种的多点、多播期和人工气候箱模拟试验结果表明，影响稻米糊化温度的主要气候因子是环境温度；日辐射的影响主要是通过改变环境温度而间接起作用的；其他气候因子有一定的影响，但不显著，且品种间反应不一致；抽穗后２０ｄ内环境温度对稻米糊化温度的影响较大，抽穗前１０ｄ和抽穗２０ｄ后的影响较小。
The multiple locations ,multiple sowing dates and psychrometric roomfor 8 rice varieties were experimented.The results showed that the effect of clmatic fac-tor on rice glatinization was the principal environmental temperature,and that solar radi-ation had a direct effect upon rice glatinization only through changing environmentaltemperature,and that other climatic factors also had some effects upon rice glatinizationbut the reactions among rice varities were different.The effect of environmental temper-ature 20 days after heading upon rice glatinization was great,but that 10 days beforeheading and 20 days after heading upon rice glatinization was small.
