Abstract:

The seed of Chinese cabbage were treated with 0，10，50，100，150，200 and 300 mg/L of oligochitosan for 24 h，exposed to matrix that include 20 mL 2.5 mmol/L Cd²⁺ solution of the 1.5 kg matrix potted plants for 7 days and then determined each index after 15 days the effects of oligochitosan on the stress of cadmium activity.The results showed that compared with the control, the activities of three protective enzymes，such as superoxide SOD，POD and CAT increased；root activity，the content of soluble sugar and chlorophyll content rised；while the MDA content and leaf relative electrical conductivity decreased in the leave of treated plants.The concentration of oligochitosan at 150 to 200 mg/L showed the most effective result.
