Performance Evaluation of Some Grape Varieties Growing in Different Altitude Groups

Abstract

This study was carried out in 3 different altitude groups (800 m, 1000 m, and 1200 m) under farmer vineyards in Malatya province in 2017 in order to determine the effect of altitude on some quality parameters of grapes. In all of the mentioned altitude groups, 4 table grape, three wine grape, and three raisins grape, a total of 10 grape varieties were evaluated. The pomological and some biochemical properties of the clusters and grains of the related grape varieties were investigated. As a result of the analysis, although it changes according to the grape variety and altitude group average bunch weight 77.6-693.27 g, bunch width-length 6.67-15.70 cm and 9.47-24.97 cm respectively. Grain weight, grain width, and flesh hardness were found to have average values such as 2.19-5.49 g, 12.66-19.66-15.31-29.51 mm, and 1.39-5.22 N, respectively. The pH varied between 3.45 and 4.56 cultivars, and the difference in the Ağın Beyazı cultivar was statistically significant only on the basis of altitude. It has been determined that fruit WSDM (Water Soluble Dry Matter) and TA (Titratable Acid), which are among the biochemical properties values have a positive correlation with the increase in altitude. © 2021, Centenary University.
