Physico-Chemical Characteristics of Some Gilaburu (Viburnum Opulus L.) Genotypes

Gilaburu is an important fruit species in terms of healthy effects, having potential for use as alternative medicine and suitable 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. In addition, correlations among the investigated characteristics were calculated and their potential to be handled together was revealed. According to results, Fruit width, fruit length and fruit weight characteristics varied between 7.40-7.95 mm, 7.65-8.81 mm and 0.30-0.37 g, respectively. Genotype 3 showed the highest values in terms of pomological characteristics, while the lowest values were obtained from Genotype 1. Among the chemical properties; pH, soluble solid 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 of positive correlation was found between fruit width and fruit length (r = 0.73 ***). Also, these properties have been found 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.
