Relationships Between Physical and Chemical Properties With Stoma Properties in Some Local Grape Varieties (Vitis Vinifera L.)

Abstract

The aim of this study was to determine the stoma densities and sizes of 12 local grape varieties grown in Yuksekova (Hakkari) province, as well as to determine the relationships between stomatal properties with physical and chemical properties. In order to determine stoma properties, leaf samples were taken from 4-5 th nodes of the summer shoots of each variety and stoma densities and sizes were determined by nail polish method from different parts of the leaf surface (bottom, middle, tip). It was determined that stoma densities were between 166.13-247.12 pcs mm(2), stoma lengths were between 22.63-27.88 mu m, and stoma widths were between 14.59-19.00 mu m. A significant positive correlation was found between stoma density with leaf size and cluster weight, and a significant negative correlation was found between stoma density with soluble solids content in grapes.
