Determination of phytochemical properties in genetic materials collected from grapevines (Vitis spp.) found in natural flora of ganos mountains

Abstract

Natural flora of Ganos Mountains in the Thrace region has an old and well-established viticulture and is a spreading area of natural hybrids. This research was performed to determine properties of grape and cluster and phytochemical properties of berries of 103 grapevine genetic materials (Vitis spp.) adapted to natural flora of Ganos Mountains in Thrace region of Turkey during the 2014 growing season. But physical measurement and chemical analysis were performed only in grapes from 31 grapevines that carried clusters during their maturity periods. Results revealed that 29,04% of grapevines examined had table grape properties (Vv43, Vv52, Vv54, Vv56, Vv57, Vv61, Vv62, Vv83, Vv100) and 70,96% of grapevines examined had wine grape properties (Vv6, Vv18, Vv23, Vv24, Vv27, Vv44, Vv45, Vv51, Vv55, Vv59, Vv63, Vv65, Vv66, Vv74, Vv75, Vv84, Vv87, Vv88, Vv91, Vv92, Vv98, Vv101). In terms of phytochemical properties of grapes from examined grapevines, while the highest total phenolic compounds content and total anthocyanin content in grapes were respectively 5609,44 mg/kg for Vv88 number of grapevine and 2602,56 mg/kg for Vv74 number of grapevine; the highest total tannin content in grapes was recorded for Vv18 number of grapevine as 5557,10 mg/kg. Since the natural flora of Ganos Mountains in Thrace region is a place where the viticulture has been conducted intensely for many years; identification of phytochemical properties in grapes of genetic materials obtained from this region is of importance in terms of future studies. © 2018 Namik Kemal University - Agricultural Faculty.
