Determination of Boron in Grape (Vitis vinifera) by Azomethine H Spectrophotometric Method

Abstract

Boron content of 10 grape (Vitis vinifera) varieties was determined by using Azomethine
H spectrophotometric method. The grape samples have been taken from Adana and Niğde region
of Turkey. The results varied between 0.59 and 9.51 mg.kg-1. Consequently, the differences have
been found in boron content of five regions’ (Kamışlı, Armutlubağ, Bozyer, Bağaltı, Çatılıyer)
grape varieties. The highest boron content was in Armutlubağ region. Results revealed that the
Turkish grape is a good natural source of boron.
