Girdling can promote anthocyanin accumulation in grape berries. However, the underlying mechanism is unclear. In this study, we explored the effects of girdling on the accumulation of anthocyanins and the transcript levels of key genes in anthocyanin synthesis in spine grape skins. We also determined the effect of girdling on the contents of vitamin C, titratable acids, soluble sugars, and aroma compounds, and the transcript levels of genes related to sugar transport and aroma compound synthesis. The girdling treatment promoted anthocyanin accu...
