| Abstract: | Allelopathy of water extracts from seeds of Mirabilis jalapa L.on watermelon and chinese wolfberry were examined for the objective of providing the reference for the theoretical study of allelopathy.By using the techniques of laboratory bioassay,the effects of water extracts from seeds of Mirabilis jalapa L.on seeds germination and seedlings growth of watermelon and chinese wolfberry were studied.The results showed: Treated with different concentrations water extracts from seeds of Mirabilis jalapa L.on seeds germination and seedlings growth of watermelon could be inhibited,and on germination of seed,height,fresh weigh and fresh weight of root of chinese wolfberry could be promoted,the inhibition or facilitation increased with increased concentrations of the water extracts. |
