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.

Gilaburu, which performs better in continental climate, has a plant height of 1.5-3.5 m and its fruits are long-living. In recent years, with the increasing demand for natural products, studies on species with high nutritional value and health importance are increasing (Polat et al., 2018; Gündeşli et al., 2019; Güney, 2020; Okatan, 2020). Gilaburu is one of the remarkable species in this context. When the studies are examined, it is observed that gilaburu fruits are rich in phenolic compounds such as caffeic acid, chlorogenic acid, ellagic acid, p-coumaric acid, gallic acid, protocatechuic acid, ferulic acid, rutin, syringic acid, quercetin, catechin, epicatechin, cyanidin-3-glucoside, pelargonidin 3-glucoside (Zarifkhosroshahi et al, 2018). Thanks to its rich and diverse biochemical content, it has been demonstrated with different studies that it has high antimicrobial, antioxidant, antimutagenic and pharmacological effects (Bolat and Özcan, 1995; Gerçekçioğlu, 1999; Burnaz et al., 2010; Murathan et al., 2018; Taşkın et al. , 2019; Yıldız and Ekici, 2019). It has been reported that its seeds also show the same effect (Güleşçi, 2019). In addition, within a study conducted on air pollution, it has been emphasized that the production of this Cite this article as: Polat, M., Mertoglu, K., Eskimez, I. (2021).
