摘  要:
以小冠花和蛇鞭菊种子为试材,研究了98%浓硫酸处理不同时间、不同浓度的赤霉素、不同温度的温水浸泡处理对小冠花和蛇鞭菊种子萌发的影响。结果表明:98%浓硫酸浸泡处理小冠花种子20min效果较好,第5天开始发芽,发芽率达92.7%。3种处理方法对蛇鞭菊种子的发芽促进作用很小,均无显著差异,其中用清水浸泡24h的蛇鞭菊发芽率最高,为77.3%,因此更好的促进蛇鞭菊种子萌发的方法还有待进一步研究。

摘  要:
Taking Coronilla varia L.and Liatris spieata Willd as materials,the effect of soaking in 98% sulfuric acid for different time,different concentration of GA3,different temperature warm water on germination of Coronilla variaand Liatris spieataseeds were studied.The results showed that Coronilla variaseeds soaked in 98% sulfuric acid for 20min was better,it germinated on fifth day and come up to 92.7%.3kinds of treatment methods on germination of Liatris spieata seed promotion effect was very small,were not significance different and the germination rate of Liatris spieatafor water 24h was the highest(77.3%).The better way to promote the Liatris spieataseed germination should be further researched.
