摘要: 试验选用甬砧1号、甬砧3号和甬砧8号三种不同砧木,嫁接早佳 (8424)西瓜品种,自根苗作对照。测定开花后35 d果实的可溶性固形物、可溶性糖、有机酸含量,以及酸性转化酶、中性转化酶、蔗糖合成酶、蔗糖磷酸合成酶的活性,研究不同砧木嫁接对西瓜果实品质的影响。结果表明,不同砧木处理的西瓜果实果糖、葡萄糖含量与对照相比显著降低,可溶性固形物、蔗糖、Vc含量提高,草酸含量、酸性转化酶活性较对照低。

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
