| 摘 要： | 该文研究了不同时间、不同浓度的赤霉素处理对‘粉红朱砂’和‘虎丘晚粉’两种露地栽培梅花的花期、展叶期和落蕾率的影响。结果表明 :2 0 0 0mg L的赤霉素在 10月底至 11月处理可使‘粉红朱砂’的花期提前约 1个月 ,展叶期提前 30～ 4 1d ,但同时出现明显的落蕾效应 ;而 1月处理使‘虎丘晚粉’始花期、末花期均延迟 ,同时开花量增加 ,且观赏期延长。研究还探讨了温度作为梅花开花的主导因子对试验研究的影响。

| Abstract: | The effects of treatment time and concentration of gibberellin on the flowering time, first leaf expansion time, and percentage of bud falling of Prunus mume `Fenhong Zhusha' and `Huqiu Wanfen' were studied in this paper, conclusions were drawn as follows: when treated by gibberllin 2 000 mg/L in late October and November, the blooming season of Prunus mume `Fenhong Zhusha' was postponed by about 1 month, first leaf expansion time was postponed by 30 to 41 d, and there was obvious bud falling; while when treated in January, both the first and the last flowering time of `Huqiu Wanfen' was prolonged, and the flowering percentage increased and period of flowering time was lengthened. Effects of temperature as the major factor in the flowering time of Mei flower was also discussed. |
