Effects of Different Exogenous Substances on Shoot Growth and Fruit Quality of'Sweet Sapphire'Grapes
摘要
Abstract
Taking'Sweet Sapphire'grape(Vitis vinifera L.)as the experimental material,six treatments were established,CK(water),T1(PBO),T2(potassium phosphite),T3(prohexadione-calcium),T4(growth-control regulator),and T5(paclobutrazol).Shoot growth,leaf chlorophyll fluorescence parameters,leaf chlorophyll content,and internal and external fruit quality of'Sweet Sapphire'grape were determined.Correlation analysis was conducted to explore the relationships among the measured indices,and principal component analysis was used for comprehensive evaluation and ranking.The effects of different exogenous substances on shoot growth and fruit quality of'Sweet Sapphire'grape were investigated,in order to provide a reference for rational growth regulation in production.The results showed that prohexadione-calcium(T3)significantly increased actual photochemical efficiency(Y(PS Ⅱ)),electron transport rate(ETR),hueangle(h°),single-grain weight,transverse and longitudinal diameters,fruit shape index,soluble solids content,sugar-acid ratio,vitamin C content,and anthocyanin content compared with the other treatments.The comprehensive scores obtained by principal component analysis ranked the treatments as T3＞T1＞T4＞T2＞CK＞T5.In conclusion,prohexadione-calcium effectively inhibited excessive shoot growth,significantly improved chlorophyll fluorescence parameters,promoted fruit growth,and enhanced internal fruit quality,showing the best growth-controlling effect among the tested treatments.关键词
