CHARACTERISTICS SEED GERMINATION AND SEEDAGE OF PRITOBOLIE WESTERN SIBERIA OF CALLUNA VULGARIS (L.) HULL
There are the results of experiments of seeding Calluna vulgaris from pine forests of Western Siberia (northern forest-steppe subzone) in this article. It is shown that seeds production of heather relic populations from this region is lower than at European part of the areal. It was found that at the northern forest-steppe under the forest canopy of Pinus sylvestris the average yield of C. vulgaris at several times lower, than on open deforestation. Perhaps, the main reason of forming the seedballs is illuminance. Nevertheless the quantity of seeds in the heather population under the forest canopy sufficiently to it reproducing. In materials of the article present the results for the germination of heather seeds in the natural conditions and in laboratory conditions. The resumption of the heather population is possible only after the fires in the pine forests. Fires burn Pleurozium schreberi moss layer which may prevent seed germination due to moister deficit and illumination shortage. The absence of the mycorrhiza leads to delay of the heather germination and the formation of underdeveloped root system.
