| Abstract: | The influence of water extracts at 0.25%,0.8% and 2.5% from roots,stems,leaves and flowers of Eupatorium adenophorum had been conducted on the seed germination and seedling growth of Brasica chinesis.The results showed that extracts inhibited the seed germination and growth of plantlet of B.chinesis,the extracts from leaves had the maximum inhibition,then the extracts from stems,and the extracts from flowers showed the minimum inhibition.The inhibition increased along with the concentration of extracts,the maximum inhibition was found at 2.5%. |
