Abstract: Fusarium wilt (Fusarium oxysporum f. sp. melonis) is one of the most serious soil-borne diseases in melon production, which has caused great losses. Nowadays, the grafting cultivation by using resistant rootstocks has become the most effective way for solving this problem. In order to apply this grafting technology efficiently, three grafting methods, i.e. hole insertion grafting (HI), pith-cambium grafting (PC) and root pruning hole insertion grafting (RP), were used to study the effect of grafting methods on grafting working efficiency, seedling growth and fruit quality by using rootstock variety Sizhuang No. 10 and melon variety Dongfangmi No.1. It was found that the grafting speed of HI and PC were quite similar, but higher than that of RP significantly, the survival rate of seedling in PC was lower than that of HI and RP significantly. According to the seedling height, scion diameter and the biggest leaf size, the seedling quality of RP was better than that of HI or PC. There was no significant difference between PC and HI in seedling quality, except the seedling height, which was lower in PC than that of HI significantly. No obvious difference was found in plant characters among the three grafting methods, including fruit setting position, internode length, leaf character of the biggest leaf. Furthermore, there was no significant difference in fruit weight, fruit shape index, pulp thickness and total soluble solid content of the fruit center among the three grafting methods. Moreover, the fruit weight of PC and RP were higher than that of own-rooted seedling significantly, the fruit shape index of grafting seedling was somewhat lower than that of own-rooted seedling, and total soluble solid content in grafting seedling was significantly higher than that of the own-rooted seedling.
