摘要: 研究红灯甜樱桃生长期喷施不同浓度(20、60、100 mg·L-1)赤霉素(GA3)对果实品质及解剖结构的影响。结果表明,60 mg·L-1的GA3处理增加了单果重与纵径。不同浓度GA3处理对果实横径无显著影响,但降低了果实硬度、可溶性糖、维生素C和可溶性固形物含量,升高了可滴定酸含量,致果实品质总体下降。解剖结构结果表明,GA3喷施浓度越大,果实角质层与表皮厚度越薄,果肉细胞与表皮细胞越大,硬度越小。建议在生产中减少GA3的使用,尤其是高浓度(100 mg·L-1)的GA3喷施对果实不利。

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
