摘　　要：[目的]研究不同处理对姜花属杂交种子发芽率的影响。[方法]分别用0(CK)、50、100、150、200 mg/L GA3浸泡种子,在24和28℃下进行发芽试验。[结果]经100 mg/L GA3浸泡后的杂交种子在28℃下发芽率最高,达97.6%。[结论]GA3处理可显著提高种子发芽率。[Objective]The aim was to study the effects of different treatments on the germination rate of Hedychium hybrid seeds.[Method] The seeds of Hedychium hybrid were treated by 0（CK）,50,100,150,200 mg/L GA3,and the effects of GA3 concentration and temperature on the germination rate were studied.[Result] The seed germination rate of Hedychium hybrid treated by 100 mg/L GA3 was the highest under 28 ℃,being 97.6%.[Conclusion] The germination rate of the seeds of Hedychium hybrid could be significantly increased when treated by GA3.
