Other claims from this paper (15)
- Intervention effect Post-veraison water stress reduced titratable acidity (TA) of Merlot grape berries.
- Intervention effect Post-veraison water stress increased total soluble solids (TSS) and pH of Merlot grape berries.
- Intervention effect Post-veraison water stress increased total anthocyanins and phenols of Merlot grape berries.
- Intervention effect Increasing the pruning level reduced berry yield per vine, TSS and pH.
- Intervention effect Increasing the pruning level increased berry volume, weight and TA.
- Intervention effect Increasing the pruning level increased total anthocyanins and phenols.
- Intervention effect The highest berry volume, weight and TA were found in severely pruned grapevines with adequate water supply.
- Intervention effect Minimally pruned grapevines under intense water stress had the highest TSS and pH of grape juice.
- Intervention effect Maximum total anthocyanins and phenols, in concentration and content, were observed in severely pruned grapevines under intense water stress.
- Intervention effect Berry yield per grapevine was higher in minimally pruned grapevines with adequate water supply, possibly due to a larger number of nodes per vine.
- Intervention effect The interactive effect of pruning level and post-veraison water stress significantly altered all measured parameters except berry weight, which responded to the main effects of the two factors.
- Association TSS had a strong negative relationship with berry volume, weight, yield and TA.
- Association pH had a strong positive relationship with TSS.
- Association Total anthocyanins and phenols were inversely correlated with berry yield per grapevine.
- Recommendation The authors conclude that combining pruning levels and water stress is a powerful tool to balance berry development and composition.
