Late summer pruning improves the quality and increases the content of functional compounds in Fuji apples

The objective of this paper was to evaluate the effect time summer pruning on quality Fuji apples, red color and functional properties, at harvest after 3.5 months cold storage. treatments evaluated consisted control (without pruning) in December, January, February. percentage fruit with more than 50% skin 20.5% higher when performed later early. In general, January February provided a relatively high content anthocyanins (19 25.1 mg cyaniding 3-glycoside·100 g-1 FW, respectively), values total phenolic compounds (370.1 438.7 EAG·100 respectively) antioxidant activity by 2,2-diphenyl-1-picrylhydrazyl (DPPH) method (8,097.5 8,089.2 µMol Trolox·100 2017/18 season. Summer did not affect or increased improved color, while it flesh firmness.
