Abstract：To study the efects of grafting onthe growthandqualityof autumn-delayed watermelon，using random block design，takinggourdandwild watermelonasrotstocks，Guihongyu watermelonasscion，andself-rootedseedlingsas control，the grafting experiment wascarredouttoinvestigate theeffectsofgraftingonmain stem length，stemdiameter， disease rsistance，yield andqualityofautumn-delayed watermelon，soas toprovide technical basis forautumn-delayed watermelon production.Theresults showed that grafting can significantly improve thegrowth potential，disease resistance，single fruit massand yield of autumn-delayed watermelon.The yield of grafted seedlings was 87.7% -1 15.7% higher than that of self-rooted seedlings，and the yield of gourd grafted seedlings was 115.7% higher than that of self-rooted seedlings.Graftingcan increase the pelhardness whilereducing the pee thicknessandflesh hardness，thereby improvingfruit storageand transportation and tastequality.Grafting could notincrease the soluble solidscontentof autumn-delayed watermelon，butgourdrootstockcould increasethecontentoffructose，sucrose，lycopene，vitaminCandtheratio offructose to glucose（F/G），thus improving the flavor qualityandnutritional qualityof autumn-delayed watermelon. Wild watermelon rootstocks significantlyreduced thecontent oflycopene，vitamin C，citrullineand theratiooffructose to glucose（F/G），thusreducing theflavorqualityand nutritionalquality.Insummary，the growth，yieldand fruit qualityof the gourdgraftedsedlings were beterthanthoseofthewildwatermelongraftedseedlings，therefore，gourdis moresuitable as a grafting rootstock for autumn-delayed cultivation of watermelon than wild watermelon.
