In order to study the effect of grafting on growth and fruit quality of melon under deficitirrigation the experiment was conducted as a split plot in a randomized complete block design with three replications during 2014 on the experimental farm of Imam Khomeini Higher Education center of Jihad-e-Keshawarzi in Karaj. Treatments consisted arrangement of four grafting (melon grafted on Shintozwa and Ferro-RZ, self grafted and ungrafted melon) and three irrigation levels 60, 80 and 100 percent, based on total available water depletion. The mean comparision showed that maximum (25.54 mg/g FW) and minimum (16.98 mg/FW) sucrose content of fruits was obtained in non-grafted plants under irrifation 80% and Souski Zard grafted on Souski Zard in irrigation 60% respectively. Also, the maximum (13.2%) and minimum (8.48%) of soluble solids was related to fruit of non-grafted plants under 80% irrigation level and non-grafted plants in irrigation 60%, respectively. The highest (7.58) and the lowest (5.29) learn points by the jury (panel test) related to fruit quality were irrigation 80 and 60 percent respectively. Also, there was no signifincant difference between deficit irrigation 80% and irrigation 100% in terms of total phenol content of fruit. The results showed that the fruit harvested from Soski Zand plant grafted on Shintozwa had better quality compared to control plants under deficit irrifation.

The effects of grafting under conditions of deficit irrigation, on content of minerals leaf and root, evalutate in a field experiment under deficit irrigation was conducted with Split plot in a randomized complete block design with three replications, in the research field of higher education institution Imam Khomeini (RA) under the Ministry of Agriculture in Karaj, during 2014. In this study, a landrace melon from Inodorus group (Zard-e-Jalali) as the scion and commercial varieties of Cucurbita rootstocks cv., ‘Shintozwa’and ‘Ferro-RZ’was used as the rootstock. Grafted melons upon commercial varieties of Cucurbita with own-rooted and ungrafted at three irrigation levels 60, 80 and 100 percent based on total available water depletion with drip irrigation system were evaluated. Comparison of means showed that maximum (40.76 ton.ha-1) and minimum (31.16 ton.ha-1) total yield, related to ‘Shintozwa’rootstock and self grafted respectively. The results showed that the irrigation levels and rootstocks had a significant effect (P <0.01) on Leaf and root mineral concentration. Also, content of minerals of leaves and roots decreased with increasing water stress. There was not significant difference in the level of 5 percent, in relation to total nitrogen of leaf between ‘Shintozwa’and ‘Ferro-RZ’rootstocks.The comparison of means showed highest (2.97 percent on a dry matter basis) and the lowest leaf total nitrogen (2.23 percent on a dry basis), respectively, in plants that grafted on ‘Shintozwa’and own rooted. The percent increase in leaves mineral elements, contain nitrogen, phosphorus, potassium and zinc in Zard-e-Jalali grafted upon ‘Shintozwa’ rootstock in compared to ungrafted plants was 26.92, 13.15, 17.88 and 15.76 percent, respectively.
