Impact of altitudinal gradients on biochemical traits and fatty acid profiles of Iranian hazelnuts.

ABSTRACT: This study investigates the influence of altitudinal gradients on the fatty acid composition, antioxidant capacity, flavonoid and phenolic content of eight hazelnut cultivars. Samples were collected from orchards at low (0-500 m), mid (500-1000 m), and high (> 1000 m) altitudes in Gilan province of Iran. Duncan's test (p ≤ 0.01) revealed that altitudinal gradients were significantly alternated the antioxidant capacity, phenolic, and flavonoid contents of hazelnut cultivars. With increasing altitude, a decreasing trend in the antioxidant capacity (ranged from 74.33 to 27.33%) and phenolic content (ranged from 380.22 to 104.68 mg GAE/ 100 g dw) was observed. In contrast, a fluctuating trend in flavonoid content was ranged from 60.33 to 170.99 (mg QE/g dw) across altitudinal gradients; subseq
