Abstract：This paper uses quality improved pumpkin‘Jingxinzhen No.5’and stress resistance enhanced Cucurbita ficifolia as rootstock,and cucumber(Cucumis sativus L.)cultivar‘Jinyou No.35’as scion.Under single-stock and double-stock conditions in greenhouse,the plant growth,water and fertilizer utilization efficiency,yield and quality of these 2 different grafted cucumbers were analyzed and compared.The results showed that the plant height,stem diameter,leaf numbers,the largest leaf areas,chlorophyll and carotenoid contents of double-stocked plants were significantly increased;the water use efficiency and contents of uptake N，P，K，Ca,Mg of grafted plants were remarkably higher than those of own-root plants.The yield and fruit number per plant,the single fruit quality of double-stock were significantly higher than‘Jingxin No.5’and own-root treatments.The single-stock increased the fruit stalk length,while double-stock relieved this tendency.Double-stock could significantly increase solution sugar content.The VC contents and sugar-acid ratio were also higher than that of C.ficifolia and own-root treatments.In term of the first female flower node,root activity,fruit length,fruit width,L/D index,and moisture content,graft treatment exerted no effect on them.The above results demonstrated that double-stock possessed characteristics of‘Jingxin No.5’and C.ficifolia,promoted water and fertilizer absorption,and could improve plant growth vigor,yield and quality.So double-stock was the best grafting combination.
