Özet

In recent years, climate change and global warming have become significant factors in viticulture, as in many plant cultivations.

High-altitude cultivation affects grapevine physiology and composition, offering alternatives for improved viticulture.

The aim of this study was to determine of the phenolic content, antioxidant activities and pomological characteristics of

commercial table grape varieties ‘Red Globe’, ‘Autumn Royal’, ‘Victoria’ and local varieties ‘Razakı’ and ‘Tilki Kuyru˘gu’

and ‘Göde Büzgülü’ that are widely grown on the plateau of Antalya in Turkey. Our results showed that ‘Red Globe’

grape variety was found to be the best among the varieties, recommended for its optimal combination of yield and quality.

Additionally, the variety ‘Red Globe’ exhibited the highest syringic acid content. The highest (+)-catechin and (–)-epicatesin

contents were found in the variety ‘Autumn Royal’, followed by the variety ‘Razakı’. The variety ‘Victoria’ showed

the highest t-resveratrol value at 5.109mg 100g–1. This study marked the first research on phenolic content, anthocyanin

content, and antioxidant activities for the varieties ‘Tilki Kuyru˘gu’ and ‘Göde Büzgülü.’ ‘Tilki Kuyru˘gu’ displayed the

highest total polyphenolic and total antioxidant activities, while ‘Göde Büzgülü’ ranked second with the highest total

anthocyanin content value.
