Abstract Headspace solid phase microextraction(HS-SPME)method was used in the experiment to study the effect of grafting on the aromatic substances in the juice of melon fruit of Yumeiren and Yongtian No.6.The results indicated-that 40 kinds of aromatic components were gained by using GC-MS online search.Among these compounds,there were 32 kinds of esters,which were the important aroma components accounting for over 70.14 %-95.77 % of peak area.The total aromatic compounds and characteristic aromatic esters contents were decreased in grafted melons than the own-rooted melon.The delightful fruit aroma were lower and the aroma of fruit were thinner in grafting melon than own-rooted fruit to a certain extent.Meanwhile,the aroma components of melon were altered because of grafting.However,the effect of grafting on aroma components was different according to varieties.The total esters content in Yongtian No.6 was obviously lower in grafting melons than own-rooted melon,but it had little effect in Yumeiren.
