摘要
[目的]通过在实验室内研究了不同温度对变色锦鸡儿的发芽特征的影响。[方法]利用培养箱和培养皿对变色锦鸡儿进行发芽试验。[结果]变色锦鸡儿在25℃条件下发芽率最高,达到了66%;30℃条件下的发芽率虽不是最高,但发芽长度略高于25℃;15℃对于变色锦鸡儿的发芽率仍有负面影响,发芽率为32%;5℃在各方面表现均最差。[结论]变色锦鸡儿在25℃条件下发芽率最高,在30℃条件下发芽长度最高。
The effects of different temperature on Caragana versicolor Benth.seed germination characteristics were studied.The results showed that 25℃ was the best temperature for the seed germination.30℃ under the condition of germination rate was not high,but the germination length was significantly higher than that of 25℃.15℃ for Caragana versicolor Benth.germination rate still had a negative effect,but the germination rate and sprout length was significantly higher than that of 5℃;5℃ in all aspects of performance was the worst。
