赤霉素处理对阳光玫瑰葡萄果实生长动态及品质的影响
Growth dynamics observation and quality analysis of grape berry under different gibberellin treatments
摘要
Abstract
[Objective]To explore the growth dynamics and quality changes of Shine Muscat grape berry under diffe-rent gibberellin treatment methods,and to provide theoretical guidance for selecting optimal gibberellin treatment methods and improving the yield and quality of Shine Muscat grape.[Method]10-year-old Shine Muscat on V-shaped trellises on their own roots were used as the experimental material,with treatments including elongating cluster+seedless and fruit re-tention+expanding(T1),seedless and fruit retention+expanding(T2),and expanding(T3),with water treatment as the control(CK).The dynamic changes of fruit growth under the four treatments were measured,measuring the length of the flower clusters at 0,12,24 h,and 3,7 d after elongating treatment;determining the berry longitudinal and transverse dia-meters at ripening stage and berry single weight,volume,firmness,soluble solid content,titratable acid content,and sugar-acid ratio at 20,40,60,80,and 100 d(ripening stage)after treatments.[Result]T1 significantly increased the length of the flower clusters compared to CK after 7 d(P<0.05,the same below).Compared to CK,gibberellic treatments(T1,T2,and T3)advanced the rapid growth period of berry,with the fastest increase in berry weight and volume,as well as the fastest decrease in berry firmness between 20-40 d after T1 and T2.Gibberellin treatments significantly increased the lon-gitudinal and transverse diameters,berry single weight and volume,promoted the expansion of berry,increased the soluble solid content,and had little effect on the sugar-acid components and firmness of the berry.The berry longitudinal diameter under T2 was significantly increased by 28.1%compared to CK,with the highest single fruit weight and volume being 11.3 g and 10.59 cm3,respectively,which were significantly higher than those of T3 and CK.At ripening stage,the sugar-acid ratio of the T2 treatment was significantly increased by 22.1%compared to CK,with a soluble solid content reaching 16.40%,and the contents of fructose(63.49 mg/g)and glucose(78.66 mg/g)in the T2 treatment were the highest among the four treatments and significantly higher than those of T1 and T3.Additionally,the titratable acid content of T2 was sig-nificantly lower than that of T1 and CK.[Conclusion]Different gibberellin treatments can greatly promote the growth and development and improve the quality of Shine Muscat grape berry.Among them,the seedless and fruit retention+expan-ding treatment results in rapid growth,ensuring fruit expansion while increasing the content of soluble solids,representing the best quality,and is suitable for use in production.关键词
