It is well known that wild berries are valuable sources of nutrients, and their consumption has positive effects on human health status. They are considered as sources of phytonutrients that are thought to have, mainly to their antioxidant activity, both curative and preventive effects against a wide range of diseases. This study was conducted for quantifying the macronutrients content of four species of wild berries: Rubus idaeus L., Ribes nigrum L., Vaccinium vitis-idaea L. and Vaccinium myrtillus L., and for identifying the influence of specific climatic conditions of the harvesting area on their dry matter content. Fruits were colected from Sovata area, Cluj County, Romania, and analysis were performed in the Laboratory of the Department of Environmental Engineering and Protection, of UASVM Cluj-Napoca. Our study shows that in concerned area black currant and bilberry have the highest nutritional content in crude protein (1.18% and 1.22%, respectively), non-nitrogen compounds (15.06%, and 8.06%, respectively), and dry matter content (17.24%, and 14.9%, respectively). The multivariate analysis show that only environmental temperature and precipitation has an influence upon fruits dry matter. The above-mentioned climatic factors influence in different extent the dry matter. Thus, in black currant (R = 0.395), raspberry (R = 0.635), and bilberry (R = 0.671) their influence is lower compared with lingonberry (R = 0.940). Our study also suggests that black currant and bilberry species emphasize strong nutritional potential, and they are less influenced by the climatic conditions compared with other wild berry species.
