Abstract:

In order to compare the influence of physiological indicators and fruit quality on grafted muskmelon of different stocks and screen out the good stock for muskmelon, we carried out the experiment. The effects of different stocks on fruit quality and physiological indicators in leaves of grafted muskmelon ‘Xinshengyu’ during process of growth were studied by field experiment and physiological determination. The results showed that the contents of chlorophyll and the activities of Peroxidase (POD), Superoxide Dismutase (SOD), Catalase (CAT) and Polyphenol oxidase (PPO) in leaves of grafted plants at three growing periods were all higher than those of own-rooted plants, while the contents of Malondialdehyde (MDA) were lower. There were differences among different grafted combinations. Among the three combinations, the contents of the total soluble solids, soluble sugar，soluble protein and Vitamin C on grafted plants of oriental pickling melon stock were the highest，the own-rooted plants lower，and grafted plants of pumpkin stock were the lowest. The yield of grafted plants of oriental pickling melon stock was the highest and that of the own-rooted plants was the lowest. According to comprehensive indicators, oriental pickling melon stock was more prominent than pumpkin stock, and it could be used as good stock for muskmelon ‘Xinshengyu’.
