Peculiarities of the Male Generative Sphere in Pinus sibirica from Forest Bog Ecotopes of Western Siberia

Abstract

We studied the male generative sphere in the populations of Pinus sibirica Du Tour growing in forest bog ecosystems of the southern taiga subzone of western Siberia. Significant differences in the morphological and palynological characteristics were found in specific microclimatic and edaphocenotic growing conditions on the upland and on the ecotone between the upland and the bog.
