Evaluation of aroma characteristics in Vitis amurensis grapes across different regions by using HS-SPME-GC/MS

Abstract

Background: Aroma compounds are important secondary metabolite in grapes and play important roles in the flavor and quality of grape berries and their wines. Vitis amurensis grape belongs to the East Asian Vitis spp., with excellent cold and disease resistance, and exhibits strong brewing potential. However, it has not been effectively utilized and there is no systematic research on the aroma compounds of V. amurensis grapes.
Methods: To provide sufficient experimental evidence for the characteristic aroma of V. amurensis grape, HS-SPME-GC/MS was used to identify the aroma compounds of five V. amurensis (‘Beiguohong’, ‘Beiguolan’, ‘Shuangfeng’, ‘Shuanghong’, ‘Shuangyou’) and three interspecific hybrids (‘Beibinghong’, ‘Xuelanhong’, ‘Zuoyouhong’) grapes in Zuojia and Ji’an. The grape berries were collected at harvest in 2020, 2021 and 2022.
Results: C6/C9 compounds were the most abundant volatile compounds in all grape varieties. Good differentiation among varieties and regions was achieved by free and bound volatile compounds in OPLS-DA and O2PLS-DA. V. amurensis grapes had more abundant aroma compounds than the interspecific hybrid berries. Compared to Ji’an, the grapes in Zuojia contained higher levels of substances, including C6/C9 compounds, terpenes, norisoprenoids and alcohols. Terpenes were found abundant in ‘Beibinghong’, C6/C9 compounds, aldehydes/ketones and alcohols such as (E)-2-hexenal, hexenal, 3-ethyl-4-methylpentanol were characteristic compounds of ‘Shuangfeng’.
Conclusion: Different varieties and regions of V. amurensis grapes exhibited different characteristics in aroma compounds. The study explored the volatile profiles of V. amurensis grapes, which can provide a reference for the development and utilization of V. amurensis grapes.

Plastid genomics of Vitis vinifera L. for understanding the molecular basis of  grapevine (Vitis vinifera L.) domestication

The precise molecular mechanisms underlying the domestication of grapevine (Vitis vinifera L.) Are still not fully understood. In the recent years, next-generation sequencing (NGS) of plastid genomes has emerged as a powerful and increasingly effective tool for plant phylogenetics and evolution. To uncover the biological profile of the grapevine domestication process comprehensively, an investigation should encompass both the cultivated varieties (V. vinifera subsp. Vinifera) and their wild ancestors V. vinifera subsp. Sylvestris) across all potential sites of their distribution and domestication.

Implication of secondary viral infections on grafting success rated in nurseries

Grapevine grafting is a complex process that since the establishment of phylloxera has become mandatory for grapevine. Grafting success in grapevine nurseries considerably varies among years and batches with most variety/rootstock combinations reach a high success rate (between 75% and 90%), but some combinations show lower success rates of around 40-50%. The causes of this variation are unknown, although biotic stresses like those caused by some viral infections have been demonstrated to affect the process. European certification schemes for the vegetative propagation of the vine include five major viruses (Arabis mosaic virus, Grapevine Fanleaf Virus, Grapevine Fleck Virus, and Grapevine-associated Leafroll Virus 1 and 3).
