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.

Assessing bunch architecture for grapevine yield forecasting by image analysis 

It is fundamental for wineries to know the potential yield of their vineyards as soon as possible for future planning of winery logistics. As such, non-invasive image-based methods are being investigated for early yield prediction. Many of these techniques have limitations that make it difficult to implement for practical use commercially. The aim of this study was to assess whether yield can be estimated using images taken in-field with a smartphone at different phenological stages.
