Autotoxicity of aqueous extracts from root,stem and leaf of flowering Chinese cabbage (Brassica campestris L.ssp.chinensis var.utilis Tsen et Lee) were studied by hydroponic in different concentrations (0.5g/L,2g/L,5g/L).The results showed that in solution with aqueous extracts from roots,stem and leaf,the growth of flowering Chinese cabbage were inhibited,leaf chlorophyll concentration declined,photosynthesis rate were affected,activities of SOD,POD and CAT were changed,MDA concentration increased,thus cell membrane permeability of flowering Chinese cabbage was damaged.The autotoxicity of aqueous extracts in flowering Chinese cabbage increased with the extracts concentration increasing.
