Abstract Taking pumpkin‘ Jingxinzhen No.3’ as rootstock and muskmelon IVF117 and oriental melon IVF09 as sclon，this paper studied the influences of grafting on melon fruit growth and development，fruit sugar contents，and relative amount and types of aroma substances in ripe melon fruit. The results showed that grafting significantly increased the fruit enlargement rate and single fruit weight，and promoted the fruit development. The contents of glucose，fructose，sucrose and total soluble sugars in ripe grafted melon fruit were lower than that of own-rooted melon fruit. There were 7 new aroma compounds in grafted muskmelon fruit，accounting for 6.35% of the total composition，but 14 kinds of aroma compounds were missing，which accounted for 15.75% of total composition. The total relative content of aroma compounds in grafted oriental fruit was reduced by 24.38 percentage point，among which the content of ethyl acetate was reduced by 23.44 percentage point. The changes in kinds and contents of aroma compounds in grafted melon fruit was the main reason for flavor changes in melon.
