摘　　要：为探讨甜瓜中间砧对日光温室西瓜生长发育的影响,以‘京欣2号’西瓜为接穗‘、伊丽莎白’甜瓜为中间砧、‘德高铁柱’南瓜为砧木,研究了南瓜砧木、中间砧、甜瓜砧木嫁接对西瓜生长发育的影响。结果表明:与自根苗对比,南瓜砧木能显著增强嫁接苗长势、提高嫁接苗光合特性、增强抗病性,株高分别增长27.8%、25.5%、25.5%,茎粗分别增长42.2%、33.6%、38.5%,枯萎病发病率分别降低71.5%、57.2%、60.5%;甜瓜砧对西瓜生长发育影响不显著;甜瓜中间砧处理各项指标介于普通嫁接与自根苗之间,且显著优于自根对照。An experiment was conducted to investigate the effects of melon interstock on the growth development of greenhouse watermelon. Effects of pumpkin rootstock, interstock and melon stock on the growth development were studied, which the scions were ＇ Jingxin No.2 ＇ and the interstocks were ＇ Elisabeth ＇ as the rootstocks were ＇ Degaotiezhu ＇ . The results showed that, compared with self-root watermelon, the pumpin rootstock can obviously enhance the growth vigor and photosynthesis as well as raise disease resistance, while the impacts of melon interstock on the watermelon develop were not significant. The plant height of the grafted watermelon which used pumpin rootstock were 27.8%, 25.5%, 25.5% higher than those of self-root watermelon respectively, and the stem diameter of grafted watermelon which used pumpin rootstock were 42.2%, 33.6%, 38.5% higher than those of self-root watermelon respectively, while the incidences of Fusarium wilt of pumpin-root watermelon were 71.5%, 57.2%, 60.5% lower than those of self-root watermelon. The levels of the indicators of the watermelon which inserted the melon interstock were between those of traditional grafting and those of self-root watermelon, and were better than those of self-root watermelon significantly.
