Abstract：This study investigated the effects of three different methods of fruit setting on yield and quality of watermelon grown under protected cultivation.The treatments included CPPU treatment,artificial pollination and honeybee pollination.The plants treated with plant growth regulator forchlorfenuron (CPPU) were used as control.The results showed that compared with CPPU treatment,honeybee pollination increased marketable fruit rate and marketable fruit yield by 11.76％ and 14.99％,respectively.Compared with artificial pollination,honeybee pollination significantly increased the marketable fruit rate and marketable fruit yield by 5.56％ and 19.27％,respectively,while there was no significance difference on the fruit quality.Compared with artificial pollination and honeybee pollination,CPPU treatment had the highest peel hardness,flesh hardness and texture,the lowest peel lightness (L) value,total soluble solid content and flesh taste rank.Compared with honeybee pollination,CPPU treatment decreased fruit soluble solid content and taste rank by 5.03％ and 8.21％,respectively.Among the three fruit setting methods,honeybee pollination had the highest total soluble solid content and the ratio of total soluble solid to titratable acid,as well as taste rank,which suggested that it performed the best.Therefore,it could replace the artificial pollination and CPPU treatment for the watermelon fruit setting under protected cultivation.
