摘　　要：以仙客来为试材，研究了外源赤霉素处理对仙客来开花和生长的影响。结果表明：20mg／L和15rag／L赤霉素浓度处理效果比较好，不同浓度不但实现了花期提前，而且对仙客来的株高、冠幅均有较好的促进作用，但在开花时间上，15mg／L浓度处理的仙客来比使用20mg／L浓度处理的仙客来提前开花5～7d；25mg／L浓度处理对株高增长和花朵爆发的效果最好。用赤霉素处理仙客来不但能使其提前开花，提早15-20d上市，还能增加株高、冠幅、花朵数和花瓣长。Taking Cyclanwn persicum as test material, the effect of different concentrations of exogenous gibberellin acid on the flowering and growth of Cyclamen persicurn were studied. The results showed that 20 mg/L and 15 mg/L concentrations gibberellin treatments were better than others. This two kinds of processing made the peak earlier, and were also useful on plant height and crown width. However,on the flowering time,the effect of 15 mg/L can blossom 5- 7 days earlier than 20 mg/L does. 25 mg/L treatment had the best effect on the increase of plant height and flowers. Gibherellic acid could not only achieve 15 -20 days ahead of flowering cyclamen, but also increased the plant height, crown,the number of flowers and length of petals.
