苯并噻二唑施用对霞多丽葡萄和葡萄酒香气物质的影响
Influence of benzothiadiazole on aroma substance of Chardonnay grapes(Vitis vinifera L.)and wines
摘要
Abstract
Benzothiadiazole(BTH)induces disease resistance and affects secondary metabolism in grapes.This study aimed to evalu-ate the impact of BTH on the aroma compounds of Chardonnay grapes and wines.Chardonnay grapevines were treated with 50 mg/L BTH at veraison to investigate its impact on physicochemical parameters,phenolics,and free and bound aroma in ripe grapes and wines.Results showed that BTH treatment increased reducing sugars,pH,total soluble solids,and skin/berry ratio of ripe grapes.BTH treatment in-creased glycerol,pH,dry extract,and alcohol,and decreased the content of titratable acidity,volatile acid,and residual sugar in Char-donnay wine.BTH-treated grapes and wines had higher concentrations of total phenolics,total flavonoids,total flavanols,and total flavo-nols than CK.Moreover,BTH treatment increased the types and concentrations of straight-chain aliphatic,aromatic,branched-chain ali-phatic,terpenoids,and norisoprenoids and decreased the concentration of C6/C9 compounds in grapes and wines.Exogenous BTH applica-tion significantly enhanced the floral and fruity aroma of wines by increasing the concentrations of isoamyl acetate and β-damascenone,and attenuated the vegetal flavor.The findings of this study may offer scientific evidence to support the implementation of BTH modulation in vineyard management practices for enhancing aroma compounds in Chardonnay grapes and wines.关键词
