Screening on salt-tolerant eggplant rootstocks of tomato

Eight eggplant cultivars were used as rootstocks and effects of salt stress on the growth of grafted and self-root seedlings of tomato were studied.The results showed that the activities of superoxide dismutase(SOD),peroxidase(POD)and catalase(CAT)in leaves of grafted seedlings were significantly higher than those of self-root seedlings.The malondiadehyde(MDA)content and superoxide anion producing rate in leaves of grafted seedlings were significantly lower than those of self-root seedlings.The tomato seedlings grafted on the rootstock 07-11-5 had the poorest salt tolerance and those grafted on the rootstocks 72 and CGN-17497 had the best salt tolerance.
