摘　　要：试验选用玉美人、永甜6号薄皮甜瓜(Cucumis melo L.)作接穗,世纪星白籽南瓜(Cucurbita moschata Duch.)作砧木,以自根苗为对照,研究嫁接对薄皮甜瓜果实糖含量及蔗糖代谢相关酶活性的影响。结果表明:嫁接提高了薄皮甜瓜果肉中酸性转化酶(AI)和中性转化酶(NI)的活性,降低了蔗糖磷酸合成酶(SPS)和蔗糖合成酶(SS)的活性;降低了薄皮甜瓜果肉的果糖、葡萄糖、蔗糖和总糖的含量。Pumpkin Shijixing was used as rootstock for melon Yumeiren and Yongtian No.6 in this experiment, and the own-root plant was used as control. Effects of grafting on sugar content and sucrose-metabolizing enzymes activities of melon fruit were studied. The results showed that fructose, glucose, sucrose and total sugar content of melon fruit decreased by grafting, acid in- vertase （AI） and netutral invertase （NI） activities of melon fruit increased, sucrose synthase activities and sucrose phosphate syn-thase activities evidently declined.
