Effects of vine top shading on the accumulation of C6/C9 compounds in 'Cabernet Sauvignon' (Vitis vinifera L.) grape berries in northwestern China.

Vine top shading at veraison can reduce the accumulation of some C6 compounds in grape berries, but no consistent consequence was attained for the vine shading at pre-veraison. The findings indicate the significance of grapevine solar exposure management at veraison in controlling the level of C6 compounds in a dry-hot region like Xinjiang. © 2021 Society of Chemical Industry.
