| 摘 要： | 对杂交水稻花时习性及花时相遇状况与各温湿度因子及其温湿互作配比的相互关系的统计分析表明：开花当天及其前一天的平均温度对花时的影响较大，湿度对花时的影响因温度不同而不同；制种的父母本花时受温湿度影响程度有一定的差异；花时同步指数与温湿配比之间存在着二次抛物线回归关系，并给出了其最优回归方程。不同温湿互作配比下的比较研究表明，相对湿度在温度较高时对花时相遇的影响更大，高湿在温度较高时有利于母本花时提前和集中，却使父本花时相对延迟。

| Abstract: | Effect of climates on blooming time and correlation between index of blooming time synchremize(IBTS) and climates were analyzed statistically. The result showed that the temperature on the blooming day and the day before was the most important factor for blooming time, effect of humidity on blooming time changed with temperature. Temperature and relative humidity had different influence on blooming time of maternal plants and paternal plants. A quadratic regression existed between IBTS and temperature humidity ratio(TGU). The experiment in artificial climatic box indicated that relative humidity had more significant effect on blooming time under the condition of high temperature, that high relative humidity made maternal Author plants' blooming time earlier and more concentrated, but made paternal plants' blooming time relative later. |
