Physico-chemical characteristics of some Gilaburu (Viburnum Opulus L.) genotypes

Abstract

Gilaburu is an important fruit species in terms of healthy effects, having potential for use as alternative medicine andsuitable for industrial product processing. In this context, physico-chemical characteristics of three different gilaburu(Viburnum opulus L.) genotypes grown under the ecological conditions of Kayseri, Turkey were determined. Inaddition, correlations among the investigated characteristics were calculated and their potential to be handled togetherwas revealed. According to results, Fruit width, fruit length and fruit weight characteristics varied between 7.40-7.95mm, 7.65-8.81 mm and 0.30-0.37 g, respectively. Genotype 3 showed the highest values in terms of pomologicalcharacteristics, while the lowest values were obtained from Genotype 1. Among the chemical properties; pH, solublesolid content (SSC) and titratable acidity (TA) values ranged from 3.53 (Genotype 1) to 3.97 (Genotype 2), 10.46(Genotype 1) to 12.72 (Genotype 2) and 1.56 (Genotype 2) to 2.16 (Genotype 1), respectively. A high level ofpositive correlation was found between fruit width and fruit length (r = 0.73 ***). Also, these properties have beenfound to increase fruit weight. While a highly negative correlation was found between titratable acidity and pH(r = -0.95 ***), it was determined that the increase in fruit size and weight decreased dry matter accumulation.
