Biochemical and structural characteristics of Scots pine (Pinus sylvestris L.) in an alkaline environment

Investigations in a 75–85-year-old Scots pine stand were performed on a territory influenced over 40 years by alkaline dust pollution (pH 12.3–12.7) emitted from a cement plant. Sample plots were located at distances of 2, 3, and 5 km E of the emission source and a control sample plot was selected on an unpolluted territory 38 km W of it. We studied soil properties and the anatomical structure,...

Aging in Pinus sylvestris L. seeds: changes in viability and lipids.

Aging of Scots pine seeds (Pinus sylvestris L.) leads to changes in seed quality, such as loss of germinability, delayed growth and abnormality in developing seedlings. The knowledge of biochemical changes responsible for these aging processes is plentiful in some seeds, which are of world-wide interest, but for pine seeds these studies are rare. The aim of the present study, was to analyse pin...

Fungal Infection Increases the Rate of Somatic Mutation in Scots Pine (Pinus sylvestris L.).

Somatic mutations are transmitted during mitosis in developing somatic tissue. Somatic cells bearing the mutations can develop into reproductive (germ) cells and the somatic mutations are then passed on to the next generation of plants. Somatic mutations are a source of variation essential to evolve new defense strategies and adapt to the environment. Stem rust disease in Scots pine has a negat...

Peculiar traits of wood in a leaning stem of Scots pine (Pinus sylvestris L.)

The paper analyses biometrical and anatomical traits of wood in a leaning stem of pine trees. For study purpose, five pine trees (Pinus sylvestris L.) with a visibly leaning stem were chosen. Wood samples were taken at three different stem heights, that is, below the stem curvature, at the curvature and above the curvature. Microscopic specimens were prepared and used for the following measurem...
