This study shows that supplemental irrigation during heat waves reduces grape yield but not whole-vine carbohydrates, suggesting irrigation helps maintain vine health despite reduced photosynthesis.

This study shows that supplemental irrigation during heat waves reduces anthocyanin loss in Cabernet Sauvignon grapes, with no additional benefit from excessive watering.

This study shows that optimized irrigation during heat events improves grapevine physiology and fruit production, while excessive or insufficient irrigation harms plant function and yield.
