Abstract:
In this study, aroma compounds of grafted and ungrafted melon (Galia C-8) were investigated. Galia C-8 melon cultivar was grafted onto 7 different rootstocks [Benincasa hispida (BH), Cucurbita ficifolia (CF), Luffa cylindrical (LC), P 360, RS 841, TZ 148 (Cucurbita Hybrids) and Cucumis melo 'Kirkagac 637'(KA 637)]. Aroma compounds in ripening fruits of Galia C-8 melon were determined and 24 aroma compounds were identified by GS-MS (gas chromatography-mass spectrometry). It was found that 2- methylbuthyl acetate, Hexyl acetate and Octyl acetate were the major compounds in grafted and ungrafted Galia C-8 melon cultivar. However, ethyl hexanoate was strongly positively correlated with fruity and sweet taste and the highest content of ethyl hexanoate was determined from Galia C8 /RS 841 graft combination, while others were in trace amounts. Octyl acetate, isobuthyl acetate and butyl acetate contents of ungrafted melon fruits were higher than grafted melon fruits but 2-methyl butyl acetate content was similar both ungrafted and grafted melon fruits.
