Abstract: In this study, varieties Yongzhen No.1, Yongzhen No.3 and Yongzhen No.8 were used as rootstocks, in which watermelon variety Zaojia(8424) was grafted, and non-grafted Zaojia plants were taken as the control. Several indexes of watermelon fruits on 35 days after flowering were measured, including contents of soluble solids, soluble sugar and organic acids, and the enzyme activities of acid invertase, neutral invertase, sucrose synthase and sucrose phosphate synthase. It was aiming to explore the effects of different rootstock varieties on watermelon fruit quality. The results showed that different rootstocks significantly reduced the fructose and glucose contents compared with the control, and increased the contents of soluble solids, sucrose and Vc; whereas, contents of oxalic and acid invertase activities were decreased.

Key words: watermelon, grafting, sugar contents, organic acids, invertase
