Title

Timing of defoliation affects anthocyanin and sugar decoupling in Grenache variety growing in warm seasons

Purificación Fernández-Zurbano; Luis Gonzaga Santesteban; Ana Villa-Llop; et al. Journal of Food Composition and Analysis 2023. doi:10.1016/j.jfca.2023.105729

Other claims from this paper (7)

Intervention effect Leaf removal treatments tended to decrease sugar content compared with an untreated control.
Intervention effect Defoliation decreased flavanol and stilbene contents in berries at harvest.
Intervention effect The ELR severe leaf removal increased anthocyanin and phenolic acid contents at harvest compared with an untreated control.
Association Warming during 2022 was associated with decreased contents of all monitored flavonol groups in grapevine berries.
Intervention effect ELR was effective only for delaying ripening, by impairing sugar:anthocyanin decoupling in the 2021 season.
Association Lower kaempferol percentage was related to the sugar:anthocyanin decoupling in the 2021 season.
Recommendation Defoliation should still be applied under current warming trends in some viticulture regions.
