The treatments evaluated consisted of the control (without summer pruning) and summer pruning in December, January, and February. The percentage of fruit with more than 50% red color on the skin was 20.5% higher when summer pruning was performed later than when performed early. In general, summer pruning in January and February provided fruit with a relatively high content of anthocyanins (19 and 25.1 mg cyaniding 3-glycoside·100 g-1 FW, respectively), relatively high values of total phenolic compounds (370.1 and 438.7 mg EAG·100 g-1 FW, respectively) and total antioxidant activity by the 2,2-diphenyl-1-picrylhydrazyl (DPPH) method (8,097.5 and 8,089.2 μMol Trolox·100 g-1 FW, respectively) in the 2017/18 season. Summer pruning did not affect fruit quality after cold storage. Summer pruning performed in January or February increased functional compounds content and improved red color, while in February it increased flesh firmness.  aanthocyanins  aantioxidant activity  ahuman health  aMalus domestica Borkh  aphenolic compounds1 aSTEFFENS, C.
