Fruit storability and physio-biochemical changes during postharvest ripening of 3 kiwifruit (A. deliciosa) clones (breeding lines 79-09, 78-16 or E-30) were compared. The respiration peak appeared 7 days after harvest. Following this, fruit firmness decreased rapidly, and the soluble solids and total sugars contents increased while vitamin C [ascorbic acid] and total acids decreased gradually until the fruits reached full ripeness. The clone that stored best had a lower respiration rate and its firmness decreased slowly. Superoxide dismutase (SOD) and catalase (CAT) activities increased with the decrease in fruit firmness. The SOD:CAT ratio influenced fruit softening and decay in the later stages of ripening. A low ratio was associated with better storage quality.
