Metabolomics of Vitis davidii Foëx. grapes from southern China: Flavonoids and volatiles reveal the flavor profiles of five spine grape varieties

Abstract

The spine grapes (Vitis davidii Foëx.) are wild grape species that grow in southern China, and can be used for table grapes, juicing and winemaking. To systematically investigate the flavor profiles of spine grapes, flavonoids and volatile compounds were detected in five spine grape varieties (Seputao, Ziqiu, Miputao, Tianputao and Baiputao) using HPLC-QqQ-MS/MS and GC-MS. The content of these compounds highly depended on the variety, such as the total concentrations of anthocyanins (91.43-328.85 mg/kg FW) and free norisprenoids (2.60 to 11.46 μg/kg FW). Seputao contained relatively higher concentrations of anthocyanins, flavonols and free volatile phenols. Baiputao was characterized by higher concentrations of skin flavanols, with more terpenoids and norisoprenoids in the free form. Ziqiu had a higher concentration of bound benzenoids. Miputao had the lowest flavonols. Their characteristic flavor compounds of were subsequently revealed using multivariate statistical analysis. The results helped the producers to further develop and utilize the spine grapes.

Relationships between vineyard soil physiochemical properties and under-vine soil cover as potential drivers of terroir in the Barossa

Aims: Soils are an intrinsic feature of the landscape and have influenced culturally and economically important terroir delineation in many wine-producing regions of the world. Soil physiochemical properties govern a wide array of ecosystem services, and can therefore affect grapevine health and fruit development. These physiochemical properties can reflect a combination of factors,

Green pruning of shoots to force new sprouting of buds, in fruit set and in pea size: vegetative, productive and maturation effects, in cv. Verdejo

The context of climate crisis leads to the acceleration of technological ripening of grapes, with unsuitable loss of acidity, so various vineyard management alternatives are being considered to delay the grape ripening. The delay of the vegetative cycle towards a period of milder temperatures affects ripening, but vine behavior can vary according to the area, conduction, watering, variety, etc. A work is proposed to know the response to the green pruning of shoots, executed in fruit set and in pea size, in cv. Verdejo.
