Molecular and hydraulic responses of grapevine to water status and phenology un...

Understanding seasonal interactions among hydraulic, chemical and molecular signalling under water deficit is crucial for improving vineyard irrigation strategies under climate change and increasing water scarcity. We aimed to test how irrigation strategies and phenology affect the hydraulic adjustment mechanisms of eight fieldgrown grapevine varieties under different long-term irrigation regimes: Full-irrigate...

Impact of deficit irrigation strategies using saline water on soil and peach tr...

Sustainable fruit orchard development in arid areas is severely affected by the scarcity of fresh water. To mitigate the lack of fresh water, the use of low-quality water for irrigation is becoming a common practice in several margin areas. However, salinity is considered one of the most important environmental constraints limiting the successful crop production. Therefore, the effects of deficit irrigation str...

Grapevine aquaporins: Diversity, cellular functions, and ecophysiological persp...

High-scored premium wines are typically produced under moderate drought stress, suggesting that the water status of grapevine is crucial for wine quality. Aquaporins greatly influence the plant water status by facilitating water diffusion across the plasma membrane in a tightly regulated manner. They adjust the hydraulic conductance of the plasma membrane rapidly and reversibly, which is essential in specific p...

Phellem cell-wall components are discriminants of cork quality in Quercus suber

Cork is a renewable, non-wood high valued forest product, with relevant ecological and economic impact in the Mediterranean-type ecosystems. Currently, cork is ranked according to its commercial quality. The most valuable planks are chosen for cork stoppers production. Cork planks with adequate thickness and porosity are classified as stoppable quality cork (SQC). The chemical composition of cork is known, but ...

Can Mediterranean terroirs withstand climate change ? Case studies at the Alent...

Climate change introduced new challenges to vinegrowers in the Mediterranean areas such as the hot and dry winegrowing region of Alentejo, south Portugal. Warmer and drier conditions are harmful for grape yield and berry quality attributes and for vine’s longevity, mainly when optimal thresholds are exceeded. Therefore winegrowers are forced to move from rainfed to irrigated production systems making Alentejo’ ...

Grape ripening is regulated by deficit irrigation/elevated temperatures accordi...

Impact of irrigation regime on berry development and flavonoids composition in ...

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, ...
