RESUMO

The present study was carried out to find the effect of fruit harvesting stage (October, November and December) on the physicochemical and antioxidant properties in five kiwi cultivars (Abbot, Bruno, Allison, Hayward, Monty). Results showed that soluble solid content (SSC) and pH increased while ascorbic acid (Vit C), titrated acidity (TAD) and SSC/TAD decreased in all the cultivars with delay in harvesting. Total polyphenols (TP) were decreased while total flavonoids (TF) increased in all tested cultivars with delay in harvesting. The highest concentration of TP (2.02 mg gallic acid equivalent/g fresh weight) and TF (51.12 mg catechin equivalent/100g FW) were found in cultivar 'Allison' in the month of October and December, respectively. Antioxidant activities (AA) were genotype depended and no trend was observed with month of harvesting. Principal component analysis (PCA) showed strong correlation between Vit C, TP and antioxidant activities. Two major clusters were computed using agglomerative hierarchical clustering (AHC). All the studied important traits may be used in the breeding programmes to increase the variability for different physiochemical and antioxidative characteristics and to make suitable selections that could be acceptable to consumers.
