Zarrouk, Olfa; Francisco, Rita; Pinto-Marijuan, Marta; Brossa, Ricardo; Santos, Raquen Raissa; Pinheiro, Carla; Costa, Joaquim M.; Lopes, Carlos M.In the present study, field grown Aragonez (Syn. Tempranillo) grapevines (Vitis vinifera L.) were subjected to three irrigation regimes (conventional sustained deficit irrigation (DI), regulated deficit irrigation (RDI) and non-irrigated (NI)) during two successive seasons (2007–2008). An integrative study was performed in grape berry skin tissues at four phenological stages of grape berry (pea size, véraison, ...
Impact of water deficit on grape seeds proanthocyanidins and antocyanins biosyn...
Santos, Raquen RaissaMestrado em Biologia Funcional - Instituto Superior de Agronomia ; Proanthocyanidins and anthocyanins are polyphenolic secondary metabolites synthesized via the flavonoid pathway. They are considered as important determinants of quality in red grapes and contribute to taste and colour in wines. As most of these compounds accumulate in seeds, these play a key role during the process of making wine. The present ...
