Abstract
The effects of NaCl stress on the growth,membrane lipid oxidation and the contents of osmoregulation substance of grafted plants and scion-root plants of mini-watermelon were studied with a salt-tolerant cucurbit variety Chaofengkangshengwang as the root stock and a nonsalt-tolerant mini-watermelon variety Xiuli as the scion.It was shown that under NaCl stress,the grafted seedlings got lightly inhibited,the superoxide dismutase(SOD),peroxidase(POD),catalase(CAT) and ascorbate peroxidase(APX) activities in the leaves of the grafted plants were significantly higher than those in the leaves of scion-root plants,the O-2·producing rate and malondialdehyde(MDA) content in the leaves of the grafted plants were significantly lower than those in the leaves of the scion-root plants,and the membrane lipid oxidation in the grafted plants was weaker than that in the scion-root plants;the contents of such osmotic substances such as free proline,soluble protein in the leaves of the grafted plants were significantly higher than those in the leaves of the scion-root plants.The above results proved that the grafted plants performed better in salt tolerance than the scion-root plants.
