摘  要:
用CaCl2(0.1%、0.2%、0.3%),PEG-6000(1%、2%、3%),KNO3(0.5%、2%、4%)溶液处理藏茵陈类植物中的川西獐牙菜Swertia mussotii野生种子和椭圆叶花锚Halenia elliptica野生种子(24或48 h),先常规发芽试验,选择平均发芽率较高的处理方法处理供试种子,然后引入土壤基质在大田中进行播种育苗。结果表明:各药剂极显著提高椭圆叶花锚种子发芽率(P<0.01),其中以CaCl2溶液促进效果最佳(发芽率70%以上,出苗率50%以上);1%、2%、3%PEG-6000溶液可提高川西獐牙菜种子发芽率及出苗率(均不及15%)。

摘  要:
The seeds of Swertia mussotii and Halenia elliptica were treated with CaCl_2(0.1%,0.2%,0.3%),PEG-6000(1%,2%,3%),KNO_3(0.5%,2%,4%) and water as control(24 or 48 h).The best treatment with the highest average germination rate was selected on the basis of Petri dish germination test at 25 ℃ in incubator.The germinated seeds from the best treatment were then transferred to the field.The results showed that each treatment significantly increased germination rate of Halenia elliptica seeds,CaCl_2 was the most effective with more than 70% germination rate and 50% seedling rate.PEG-6000 (1%,2%,3%) could increase germination and seedling rates of Swertia mussotii,but with lower percentage(less than 15%).in the field.
