Variations in antioxidant activity, total phenolic, anthocyanin, and flavonoid content in fruit samples among genotypes was much greater than the variation observed between growing seasons, indicating that genetics plays a more important role than growing season in V. arctostaphylos fruits. The data indicated that the fruits of the Kelardasht genotype had the highest total phenolic content [ ± mg gallic acid equivalents (GAE) g-1 DW], anthocyanin content ( ± 76 mg g-1), and antioxidant activity while the Masouleh genotype had the lowest antioxidant activity. Significant main effects for genotype, growing season, and genotype × growing season were observed for anthocyanin and antioxidant activity, while variation in polyphenolic content indicated that genotype plays more of a role than growing season in the leaves of V. arctostaphylos. Correlation analyses indicated that there was a linear relationship between antioxidant activity and the total phenolic and anthocyanin content in fruits and leaves. Over both growing seasons the flavonoids did not play an important role in the .
