Crop forcing technique and irrigation strategy modified the content and phenolic profile of cv. Tempranillo grape berries grown in a semi-arid climate.

Background: Climate change modifies the content and phenolic profiles of grapes and wines. It is known that high temperatures, related to climate change, reduce anthocyanins and procyanidin (catechin and tannin) compounds accumulated in the berries. In recent years, with the aim of improving the phenolic composition of the berries, the technique of crop forcing has been proposed to delay grape ripening to a more favourable period of temperatures.

Vine Irrigation through Two Shoot Densities in Flavonoid and Non-Flavonoid Compounds in 'Tempranillo' Grapes.

This study aims to analyze the effects of non-limiting irrigation () vs. rainfed () through two different shoot densities, high-load () and low-load (), on vegetative growth, agronomic parameters, flavonoid and non-flavonoid polyphenol substances of cv. Tempranillo grown in a semi-arid climate during three consecutive seasons (2014-2016).
