Ripening grape berries remain hydraulically connected to the shoot.
Berry diameter was monitored during dry-down and rewatering cycles and pressurization of the root system of Vitis vinifera (cv. Merlot) and Vitis labruscana (cv. Concord) to test changes in xylem functionality during grape ripening. Prior to veraison (onset of ripening), berries maintained their size under declining soil moisture until the plants had used 80% of the transpirable soil water, beg...
متن کاملFruit ripening in Vitis vinifera: spatiotemporal relationships among turgor, sugar accumulation, and anthocyanin biosynthesis
This study reports the first observations indicating the spatiotemporal relationships among genetic and physiological aspects of ripening in the berry of Vitis vinifera. At the onset of ripening in the red flesh variety Alicante Bouschet, colour development began in the flesh at the stylar end of the fruit and progressed toward the pedicel end flesh and into the skin. Tissue solute potential an...
متن کاملFunctional xylem in the post-veraison grape berry.
A number of studies have shown a transition from a primarily xylem to a primarily phloem flow of water as fleshy fruits develop, and the current hypothesis to explain this transition, particularly in grape (Vitis vinifera L.) berries, is that the vascular tissue (tracheids) become non-functional as a result of post-veraison berry growth. In most studies, pedicels have been dipped in a vial cont...
متن کاملCan Raising Vitamin D Status Slow Down Covid-19 Waves?
Several mitigation and suppression policies, such as social distancing, city lockdowns, remote working, testing, providing personal protective equipment and health care resource availability have been implemented by the governments in response to Covid-19 pandemic. Until now (October 23, 2020), over 1.14 million deaths in the world including 31,650 just in Iran have been officially attributed t...
متن کاملDifferential responses of sugar, organic acids and anthocyanins to source-sink modulation in Cabernet Sauvignon and Sangiovese grapevines
Grape berry composition mainly consists of primary and secondary metabolites. Both are sensitive to environment and viticultural management. As a consequence, climate change can affect berry composition and modify wine quality and typicity. Leaf removal techniques can impact berry composition by modulating the source-to-sink balance and, in turn, may mitigate some undesired effects due to clima...
