The paper reviews the present knowledge of Scots pine (Pinus sylvestris L.) diversity, historical and geographical distribution, based on mitochondrial and chloroplast DNA data. The observed differences in the estimates of genetic differentiation between different types of genomes suggest that both pollen and seed contribute significantly to gene flow within species. Organelles' diversity represents an important criterion which could be later applied in planning for future forest management and breeding through a better understanding of adaptation strategies of different Scots pine haplotypes. This analysis would provide valuable references when facing current day problems with climate change, species adaptation, and loss of forest with negative effects on biodiversity. Research on organelles' diversity could lead to important practical applications in areas such as traceability and eco-certification of forest products, and the identification of plant populations for conservation. Based on the results from earlier investigations, Scots pine in Europe can be divided into at least three evolutionary units (Spain, northern/central Europe and northern Fennoscandia), each with a different origin after glaciations. However, it must be emphasized that these interpretations are preliminary and further mitochondrial and chloroplast DNA data need to be analyzed in conjunction with evidence from pollen and fossil analysis.

Сonducted research and practical application of modern methods of molecular genetics diagnostics to de-termine different types and degrees of diseases of seedlings, including difficult to differ in their appear-ance, are examined. Phytosanitary studies have been performed on one-two-year seedlings of Scots pine (Pinus sylvestris L.) and chestnut (Aésculushippo cástanum L.), obtained from six forest nurseries both the Lipetsk and Kursk regions. The degree of different types of pathogens of received seedlings was 30 percent or more.

The Stability

The article presents the results of evaluating the growth of Scots pine in the Baymak forest area. The analysis of forestry and taxation indicators of Scots pine crops on the studied sample areas is carried out, and a comparative assessment of the growth of forest crops growing in different types of forest is given. Increased competition in plantings leads to the natural decline of stunted trees, which is the result of differentiation in the stand. As a result, its structure changes, the number of large trees increases, and, accordingly, the stability of the forest ecosystem increases. In this regard, the appearance of the tree distribution curve by thickness levels also changes. It becomes more "flat", and its competitive load is more evenly distributed over the entire structure of the stand, and competition is weakened.
