Abstract：Compared with own-rooted muskmelon Xiyu No.1 seedlings with weak hypoxia tolerance，the tolerance to hypoxia of muskmelon seedlings grafted with spong gourd and pumpkin was studied．The results showed that relative electronic conductivity，MDA content in the roots and leaves of grafted seedlings were evidently lower than that of own-rooted muskmelon seedlings under hypoxia stress.However，chlorophyll，the activity of roots，proline content and the activities of SOD，POD，CAT were evidently higher.There was a considerable difference of hypoxia tolerance between the two grafted seedlings due to the different roootstocks.The hypoxia tolerance is related to anti-oxidative ability and membrane stability in the seedlings.The results indicated that the hypoxia tolerance of muskmelon seedlings was increased through grafting with spong gourd and pumpkin.
