The role of vine trunk height in delaying grape ripening: insights for viticultural adaptation strategies

Abstract

Global changes in temperature patterns necessitate the development of viticultural adaptation strategies. One promising approach involves modifying the training system and elevating trunk height. This study explored the potential of raising the vine trunk as an adaptive strategy to counteract the effects of increasing temperatures and delay ripening. Thermal conditions, radiation levels, and must composition were measured at different heights (10 and 150 cm) in a commercial vineyard of the minority variety Maturana Blanca, trained on a vertical cordon. The results showed a significant delay in grape maturation in the upper part of the vertical cordon, characterized by lower Brix levels and higher titratable acidity than the lower section. These outcomes can be partly explained by observed variations in the Winkler index measured inside the canopy, indicating a 15.59% reduction in the upper zone. However, the radiation percentage in the fruiting zone was significantly higher in the upper part of the vine. In summary, the change in trunk height significantly impacted grape ripening. The study underscores vineyard management’s importance in improving wine quality and preserving its typicity. These findings open avenues for future research, guiding potential adjustments in viticultural practices under evolving environmental conditions.

Implications of the nature of organic mulches used in vineyards on grapevine water status, yield, berry quality and biological soil health  

Climate emergency is going to affect the agricultural suistainability, wine grapes being probably one of the crops more sensitive to environmental constraints. In this context, mitigation strategies such as the revalorization of agricultural wastes are paramount to cope with the current challenges. The use of organic mulches has been reported to reduce soil water evaporation and improve vine water status, reduce soil erosion, and increase soil organic matter with little impact on berry quality. However, less is known about their effects on the microbiote of vineyards.
