摘要
目的:研究不同温度、不同光照、不同贮藏方式和贮藏时间以及不同赤霉素浓度处理对滇龙胆种子萌发的影响。方法:观测滇龙胆种子在不同处理条件下的发芽率。结果和结论:25℃为种子最适宜萌发温度,发芽率可达76.33%。光照对种子萌发影响显著,黑暗条件下种子发芽率极低。在自然条件下,干藏为种子最佳贮藏方式,可促进种子后熟作用,保持种子活力,但不能超过6个月。100～1 000 mg.L-1赤霉素处理可明显缩短滇龙胆种子萌发时间,其中500 mg.L-1赤霉素处理可使种子发芽率提高至95.00%。
Objective：To investigate the influences of temperature,lightness,storage method,storage time,and gibberellin on seed germination of Gentiana rigescens.Method：The germination rates of G.rigescens in different treatments were observed.Result and Conclusion：The most suitable temperature for the seed germination was 25 ℃,at which the germination rate was 76.33%.The effect of lightness on the seeds was significantly;the germination rate of the seed was very low.Under the natural condition,the best storage method was dry storage（within 6 months）,which could promote the after-ripening of the seed.100-1 000 mg·L-1 gibberellic acid could significantly reduce the seed germination time,and 500 mg·L-1 gibberellic acid increased the germination rate of the seed to 95.00%.
