Effects of Lateral or Secondary Induced Shoot Use on Number of Bunches and Fruit Quality in Forcing Cultivation by Current Shoot Cutting and Flower Cluster Removal to Shift Grape Ripening to a Cooler Season

In grapes, the ripening time of bunches on lateral or secondary induced shoots, led by simultaneous treatments current shoot cutting and flower cluster removal, is typically delayed until cooler seasons. The aim this study was to estimate effects use in cultivation ‘Merlot’ grapevine phenology, including number weight, yield, fruit quality. timings flowering, coloration harvest grapes were around one month compared with those vines grown under standard cultivation, which used as a control. However, there substantial differences between terms When shoots grew after cut clusters removed, decreased, yield significantly reduced. contrast, when germinated shoot, clusters, growing stable observed not severe decrease yield. Skin anthocyanin content both grape berries increased This effect comparatively stronger subjected lower air temperatures during ripening. results underscore importance discriminating process shifting season removing clusters.
