Abstract: Objective】An experiment was conducted to investigate the effect of melon interstock on the plant growth and quality of greenhouse cucumber fruits.【Method】Comparisons were made on the plant growth, bleeding sap and fruits quality among the self-rooted cucumber, the traditional grafted cucumber and the grafted cucumber with interstock of ‘Elizabeth’ melon, which the scions were ‘Zhongnong No.14’ and the rootstocks were ‘Zhenyoumei’ pumpkin.【Result】Grafted cucumber with melon interstock grew better than self-rooted cucumber, and no significant difference was observed in comparison with traditional grafted ones. The contents of soluble sugar, soluble solids and VC in the interstock grafting were significantly higher than those in traditional grafted treatment, whereas the titratable acid content was obviously lower. Keeping two true leaves of the interstock of melon significantly increased the contents of soluble proteins and dry matter.【Conclusion】Grafting with melon interstock significantly improved the quality of cucumber fruits as well as better growth.
