In this study musckmelon landrace of ‘Tosabze Saveh’ was grafted on rootstocks that including ̔Ferro-RZ̕ and ̔Shintozwa̕, also own-rooted and ungrafted plants with three irrigation levels of 100, 80 and 60 percent (based on readily available water depletion) that water were used 5792.21, 4815.20, 3867.60 m3 ha-1 respectively for 84 days after transplanting under field experiment as split plots based on randomized complete block design was carried out in 2014 in Karaj. The analysis of variance of fruit phenol and total soluble solids were demonstrated that there was no significant difference between the rootstocks. The heighest (68.07 percent) and the lowest (59.09 percent) leaf relative water content, were found in ‘Tosabze Saveh’ grafted on ̔Shintozwa̕ and self-grafted respectively. The results showed that with increasing water stress the antioxidant capacity of fruits increased while not significant differences of the amount of vitamin C fruits there. Also it is significant difference in regarding to efficiency of photosystem II was found between the cucurbita rootstocks and control plants. The means comparisons showed that heighest (31.22 ton. ha-1) and the lowest (23.85 ton ha-1) total yield per hectare was recorded in plants that grafted onto ̔Shintozwa̕ and own-rooted respectively. Assessment the contents of mineral elements of leaves showed that the increasing percentage of total nitrogen in melon ̔Tosabze Saveh̕ grafted onto ̔Ferro-RZ̕ and ̔Shintozwa̕ in compared to control (non-grafted) were 18.14 and 19.022 percent respectively.
