Abstract

The elemental composition and its ratio in the composition of plant materials is an indicator of the adaptability and variability of plants to environmental conditions. However, there is species specificity, which necessitates the study of the mineral composition for different plant species. Squat cloudberry (Rubus chamaemorus L.) is a rare species for the Republic of Belarus wich is wanted for saving and protection, but it has a great potential. The article presents the results of the macro- and microelement composition of various parts of the cloudberry determining, it is drawn conclusions about population differences depending on the ratio of biogenic elements. The fatty acid composition of lipids of fruit seeds was determined, which varies depending on the populations and climatic conditions of growth of this species. It has been established that the dominant fatty acids in the composition of triacylglycerides are linoleic (ω-6), linolenic (ω-3) and oleic (ω-9). It was concluded that the Lonno reserve is the most optimal from the point of view of the growing conditions of this species.
