摘要
对钝萼铁线莲种子用不同浓度GA_3溶液、不同温度、不同光照、不同储存条件处理进行萌发试验。结果表明:用GA_3处理能促使钝萼铁线莲种子萌发时间提前,但对种子的发芽率没有影响;钝萼铁线莲种子在有光条件下发芽率明显高于黑暗条件;在25℃时种子具有最高的发芽率(74.67%);随着储藏时间的增加,种子发芽率显著下降。
The effects of GA_3,temperature,light,storage time and methods on the seeds germination of Clematis peterae were studied through seeds germination experiment.The results showed that the time of seeds germination shorted after the seeds treated with GA_3,but it had no effect on the seeds germination rate.the seeds germination of C. peterae was sensitive to light,it could improve the germinatioa The optimal temperature for germination was 25℃（74.67%）.With the increase in storage time,the seeds germination rate decreased.
