Abstract
Using 'King Shindosa' pumpkin (Cucurbita maxima × C.moschata) as root stock, watermelon (Citrullus lanatus (Th) Mansfeld) cultivar 'Jingxin No. 2' as scion, grafting was made to compare the differences in plant growth trends, physiological and biochemical characteristics of the leaves between grafted and self-root plants under NaCl stress. The results showed that no obvious differences in morphological indexes were observed between grafted and self-root plants at the early stage of the growth course, however,the morphological indexes of grafted plants were significantly higher than that of self-root plants. Photosynthetic rate (P_n), stomatal conductance(Gs)and intercellular CO_2 concentration (Ci)of grafted plants were significantly higher than that of self-root plants. The activities of superoxide dismutase (SOD) and peroxidase (POD) , proline content and root vigor of grafted plants were significantly higher than that of self-root plants, while malondialdehyde (MDA) content of the former was significantly lower than that of the later. Based on these results, it could be concluded that the tolerance to NaCl stress of grafted watermelon plants was stronger than that of self-root plants.
