classifications of unmarketable fruit, as well as
leaf, fruit, and soil mineral concentrations, were used to evaluate orchard productivity.
Apple fruit quality was assessed at harvest and after refrigerated (0 to 1 C) storage for
three months in regular atmosphere (ambient oxygen levels) and for three and six months
in controlled atmosphere (1.5% to 2% oxygen). Fruit internal ethylene concentrations and
evolution, fruit respiration, flesh firmness, soluble solids concentration (SSC), titratable
acidity (TA), purgeable volatile production, sensory panels, and total antioxidant activity
(TAA) were used to evaluate fruit quality
