Fruit Quality and Biochemical Characteristics of Different Strawberry Tree (Arbutus unedo L.) Genotypes Grown in Giresun

Abstract

This study was conducted to examine fruit quality, chemical and biochemical properties of 20 strawberry tree (Arbutus unedo L.) genotypes that naturally spread in Bulancak district of Giresun province. In this context, fruit size, pH, SSC (Solible Solid Content), color indices, specific sugars, Vitamin C, citric and malic acids were detected in the fruit samples of the evaluated genotpes. Fruit weight varied between 2.33 and 4.69 g, fruit width 16.85 and 20.62 mm, fruit length 14.52 and 17.93 mm, pH 3.36 and 3.88, SSC 11.60 and 19.60%. The range of the results of glucose, sucrose, fructose and total sugars were 2.32-8.34 g 100 g-1, 0.02-1.93 g 100 g-1, 3.08-17.93 g 100 g-1 and 7.17-27.18 g 100 g-1, respectively. The amount of vitamin C contained in the fruits of strawberry tree was determined as 13.53-126.60 mg 100 g-1, the amount of citric acid was 0.16-0.69% and the amount of malic acid was 0.27- 1.30%.
