Abstract: In the present study, the effect of gibberellin (GA3) on fruit quality and anatomical structure of Hongdeng sweet cherry was explored. It was shown that application of 60 mg·L-1 GA3 increased single fruit weight and longitudinal diameter. Application of GA3 had no significant effect on fruit diameter, decreased the firmness of fruit, contents of soluble sugar, vitamin c and soluble solid, yet increased titratable acid content, which led to the overall decline in fruit quality. Anatomical structure analysis showed that with the increased concentration of GA3, the thickness of cuticle and epidermis and firmness of fruit decreased, yet the size of flesh cells and epidermal cells become larger. It was suggested that the application of GA3 should be reduced in production, especially for the application with high concentration (100 mg·L-1).

Key words: sweet cherry (Prunus avium L.), gibberellin, anatomical structure, fruit quality
