摘要: 本文应用“抑花一号”研究了垂柳的花芽分化发端时间。在垂柳花芽分化发端时间前注射“抑花一号”,其芽基本上都分化为叶芽;在其花芽分化发端时间期间注射“抑花一号”,其芽部分分化为花芽,部分分化为叶芽;在其花芽分化发端时间后注射“抑花一号”,其芽基本上都分化为花芽。结果表明:在北京地区,垂柳雄花花芽分化的发端时间位于6月24日~7月9日之间,雌花位于6月29日~7月14日之间。

Abstract: The blossom-bud differentiation starting times of S. babylonica have been researched using BBRⅠ. Salix babylonica L. been injected the “No. 1 of blossom bud restrainer” (BBRⅠ) before, in period of and after its blossom-bud differentiation starting times, its bud differentiated to leaf bud, leaf bud & blossom bud, and blossom bud. The results are that the blossom-bud differentiation starting times of S. babylonica male plant are form 24th June to 9th July in Beijing, and the times of S. babylonica female plant are form 29th June to 14th July in Beijing.
