关键词：
铁棒锤;温度;光照;发芽特性
摘  要：
研究了铁棒锤(Aconitum pendulum Busch)种子在光照和黑暗条件下不同温度(10、15、20、25、30℃和23/28℃变温)处理对发芽率、发芽势和发芽指数的影响。结果表明,铁棒锤种子千粒重为1.66 g;最大吸胀率为125.0%,达到饱和吸胀需20 h;黑暗环境下15℃有利于种子发芽,发芽率达30.3%,16天内平均发芽指数达1.54,但萌发后光照有利于形成健壮的幼苗。上述结果说明,土壤温度稳定通过15℃是铁棒锤的最佳播期,播种后应采用一定的覆盖遮荫措施,出苗后及时解除遮荫以促进根系发育。

摘  要：
In order to explore the suitable environment conditions for the seed germination and provide the technical basis for its domesticated and standardized cultivation,the seed characteristics、seed germination rate、germination power and germination index were investigated under different temperatures(10℃,15℃,20℃,25℃,30℃ and 23/28℃) with or without light.The result showed that the biggest expanding rate was 125.0% in 20h with 1.66g of 1000-grains weight.The dark condition at 15℃could benefit seed germination,which reached 30.3%.Under this condition,the germination index reached 1.54.However,the light after germination were beneficial to form the strong seedling.All above results indicated that when the soil temperature is constant at 15℃,the medical plant seeds should be planted.Aftre that,the soil should be covered with shade until germination so as to improve its roots and construct strong seedlings.
