Rootstock selection and thinning treatment have long been shown to positively affect quality parameters of fruits. However, rootstock selection for high content of phytochemical in sweet cherry is in its infancy and no data are available about the effect of manual thinning on these compounds. In Experiment 1, fruit of ‘Lapins’ grafted onto MaxMa Delbard® 60 Broksec* showed the highest ripening index among the 11 rootstocks evaluated, associated with high anthocyanin, flavonoid content, and total antioxidant ability. In Experiment 2, MaxMa Delbard® 60 Broksec* was selected as rootstock for 25% and 50% of manual bud thinning treatment. Thinning increased significantly fruit size (+9.5% and +19%, respectively), solid soluble and anthocyanin content, and total antioxidant ability of drupes. Chroma and L* values decreased along with the increment of anthocyanin content. Beside the classic rootstock selection, thinning is a promising approach to further increase both organoleptic and nutraceutical properties of sweet cherry.
