Abstract:

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.
