| 摘 要： | 在花芽形态分化期喷施25mg/L、50mg/L、100mg/L GA3溶液使现蕾期提早1d、3d和1d；同样浓度的GA3溶液在花蕾膨大期施用后，显著增加了花蕾膨大的速度，并且使始花期分别比对照提前了2d、6d和6d；50mg/L的GA3溶液在花芽形态分化期喷施1次使始花期提前2d，在花蕾膨大期喷施1次使始花期提前6d，而GA3溶液2次处理后始花期提前8d。分析GA3溶液处理提前花期的生理学基础发现，GA3处理有利于顶芽中的干物质积累，并加强了可溶性糖向茎顶端转移。

| Abstract: | It was found that the time of flower budding was advanced 1 day,3 days and 1 day by 25 mg/L?50 mg/L?100 mg/L GA 3 treatments during the differentiation of flower buds .Alabastrums became more bigger and the time of first flowering was advanced 2 days,6 days and 6 days when 25 mg/L?50 mg/L?100 mg/L GA 3 were sprayed during the enlargement of alabastrums. The time of first flowering was advanced 2 days,6 days and 8 days when 50 mg/L GA 3 was sprayed only once during the differentiation of flower buds, the enlargement of alabastrums and sprayed two times. The contents of dry matter and soluble sugar were increased in the apical buds with GA 3 treatments. |
