摘  要:
分别用小花山桃草不同器官的水浸出液处理萝卜、小麦和白菜种子,对种子的萌发和α-淀粉酶含量进行了观察和测定。结果表明:小花山桃草水浸出液对萝卜、小麦和白菜种子萌发具有抑制作用,浓度越高抑制作用越强;同一浓度不同器官的水浸出液对萝卜、小麦和白菜种子萌发具有不同的抑制作用;同一器官不同浓度的水浸出液对萝卜、小麦和白菜种子萌发亦具有不同的抑制作用。

摘  要:
The allelopathic effects of aquatic extracts from Gaura parviflora on the seed germination and the α-amylase content of radish,wheat and cabbage were studied in this paper.The main results were as follows:The aquatic extracts inhibited the seed germination of radish,wheat and cabbage.The higher the concentration,the greater the effect:The concentration of the aquatic extracts from root,stem and leaf of Gaura parviflora had different effects on the germination of the tested seed;The different concentrations of the aquatic extracts had different effects on the seed germination of radish,wheat and cabbage.
