Abstract

In the present paper we analyzed the stilbene accumulation in grape canes of seven autochthonous grape varieties from Veneto region, Italy. In addition, we investigated the effect of pruning time on the stilbenes accumulation rate during the storage. Taking into account the effect of both pruning time (October, November and December) and storage time (from zero to twelve weeks at room temperature), cultivar Verdiso and Incrocio Manzoni 13.0.25 showed the highest accumulation of trans-resveratrol, trans-piceatannol, and trans-ɛ-viniferin, in particular when the canes were harvested in October, highlighting the importance of the cultivar but also the effect of the pruning time on the accumulation of stilbenes in grape canes.
