BIOMETRIC INDICATORS OF CRANBERRY (VACCINIUM OXYCOCCOS) OF BIRCH FORESTS OF THE RESERVE "OLMANSKY MARSHES" OF STOLINSKY DISTRICT

The article presents morphological and biochemical parameters of Vaccinium vitis-idaea in a birch forest. Leaf sizes, their average surface area, and biochemical composition, including chlorophylls and carotenoids, are determined. A high variability in the mass of the aboveground parts of the plants and a berry yield averaging 477.7 g/m² were observed. The data obtained are important for assessing the productivity and ecological adaptation of the plant.
