| 摘 要： | 笔者探讨不同浓度赤霉素(GA3)对地被菊‘紫重楼’ 株高、冠幅、开花特性（花期、开花量、花朵重瓣性、花径）和花粉生活力的影响，旨在为地被菊杂交育种、花期调控提供参考依据。试验结果表明，喷施100~500 mg/L GA3后，‘紫重楼’露色期、始花期及盛花期分别提前6~10天、7~12天和2~7天；GA3有利于节间伸长和株高增加，但植株开花量和花瓣重瓣性降低，冠幅、花径减小。其中，500 mg/L GA3处理下的地被菊节间长度与株高显著高于其他水平；100~300 mg/L GA3处理可促进花粉生活力，500 mg/L对花粉生活力有抑制作用。

| Abstract: | The effects of different concentrations of gibberellin on plant height,crown breadth,flowering characteristic (flowering season,flower number,petals number,flower diameter) and the pollen germination viability of ground-cover Chrysanthemum ’ Zichonglou ’ were studied,which could provided substantial base for the hybrid breeding and regulating flower season of ground-cover Chrysanthemum.The results showed that 100-500 mg/L of gibberellin might cause the dewing color season 6-10 days ahead of time,the starting flower season 7-12 days ahead of time,and the abundant flowering season 2-7 days ahead of time.With the increase of gibberellin concentration ranging from 0 to 500 mg/L,internode and plant height were increased,but the flower number,petals number,crown breadth,and flower diameter were inhibited.The longest internode and plant height occurred with 500 mg/L gibberellin treatment.The pollen germination viability were improved by 100-300 mg/L of gibberellin,and impressed by 500 mg/L gibberellin. |
