Abstract
This paper examined the allelopathy effects of aqueous extracts from Camellia oleifera on seed germination and seedling growth of Platycodon grandiflorus with different concentrations(0.005,0.010,0.020,0.030 and 0.040 g / mL).The results showed that the low concentration of aqueous extract from Camellia oleifera could promote seed germination and seedling growth.As the centration increased,the stimulating effects decreased,and even changed into inhibition.The results indicated that low concentration of aqueous extract from Camellia oleifera enhanced the root length and shoot height growth of Platycodon grandiflorus,and 0.010 g / mL treatment exhibited the optimalist allelopathic promotion effect.
