Abstract:

In Jiangsu and Zhejiang regions, typhoons or heavy rainfall often occur during the grape ripening period, causing waterlogging in vineyards and severely affecting the grapes quality. In this study, Reliance grape (Vitis labrusca L.×Vitis vinifera L.) was taken as the experimental material. The grapes were treated with waterlogging prior to veraison, and then treated with 4 g·L-1 of calcium chloride after 14 days. Total soluble solids (TSS), mainly primary and secondary metabolites contents were determined to analyze the effects of calcium treatment on the grape quality after waterlogging. Our results showed that sucrose, glucose, fructose, sorbitol and TSS contents in the grapes were reduced by 5.24%, 3.10%, 5.92%, 12.48% and 1.32%, respectively, compared with the control group, while malic acid, citric acid and tartaric acid contents were increased by 78.44%, 7.52% and 15.05%, respectively after waterlogging. Grapes treated with calcium after waterlogging, their TSS, sucrose and sorbitol contents increased by 1.23%, 5.17% and 7.34%, respectively, while the 4 organic acids (malic acid, tartaric acid, citric acid and malonic acid) contents all decreased to a certain extent. Additionally, grapes treated with calcium showed a significant increase in total anthocyanins and flavonol contents under waterlogging, as well as better coloring. In conclusion, calcium treatment can improve the grape quality after waterlogging, which has important theoretical and practical implications for the flooding resistant cultivation of grapes and fruit quality improvement in southern China.
