Radial growth of F (var) sulfuranthera Kozubow and F. (var.) erythranthera sanio pine forms (Pinus sylvestris L.) in the conditions of northern taiga soils excess moistening

Variability of radial growth of (f. (var.) sulfuranthera Kozubow) and (f. (var.) erythranthera Sanio) forms of pine in pine forests of shrub-sphagnum bog on upland soils of northern taiga is studied. Advantage in the average size of a year growth at ripe age of pine with yellow coloring of boots in comparison with red coloring of boots at pine is revealed. Temporary dynamics of width of year rings at these forms is analyzed.
