杂交水稻三系的花时与天气条件有着较密切的关系。 在晴好天气条件下,不育系在一天中开花时间总是比保持系和恢复系延迟,而且开花时间也较分散。但在阴天条件下(有时有小阵雨),保持系的开花时间显著延迟,而不育系的开花时间和集中程度与晴好天气条件下无显著差异。 表1和表2分别为我站1977年6月16日在晴天条件下和6月18日在阴天条件下于泽潭公社明星大队对春繁珍汕品种的观测结果(表中A_1,A_2,…,B_1,B_2,…,为不同观测
Hybrid rice three lines of flowers and the weather conditions are closely related. Under good weather conditions, sterile lines are always delayed in their flowering time during the day than the maintainer and restorer lines, and the flowering time is also more dispersed. However, in cloudy conditions (sometimes with small showers), the flowering time of maintainer lines was significantly delayed, while the flowering time and concentration of CMS lines were not significantly different from those in sunny weather conditions. Table 1 and Table 2 show the results of observing the Chun-Fan-Zhenshan breeds by the Star Brigade in Ze-Tan Community on June 16, 1977 under sunny conditions and June 18 under cloudy conditions (Tables A_1, A_2, ..., B_1, B_2, ..., for different observations
