The objective of the present study was to investigate the variations in some major primary (sugars and organic acids) and secondary (phenolics, β-carotene) metabolite contents during fruit development and ripening in two important apricot cultivars (Hacıhaliloğlu and Kabaaşı). The changes in the compositional properties of two apricot cultivars were monitored during fruit development with one-week intervals from 56 to 119 days after blossom. During fruit development, the contents of organic acids and phenolics decreased whereas that of sucrose and sorbitol increased. p-Coumaric acid was the only phenolic compound which increased in concentration during fruit development regardless of the cultivar. The content of the other phenolic compounds decreased in a cultivar-dependent manner. The β-carotene content of the cultivars showed distinct patterns of change such that 3 fold increase in β-carotene content of Kabaaşı cultivar was observed whereas the β-carotene content of the Hacıhaliloğlu cultivar did not show any significant change during fruit development.

Keywords: apricot; carotenoid; metabolism; phenolic; phytochemistry; ripening.
