Morphological features of male generative structures in Pinus sylvestris L. populations growing on bogs and in dry valleys in the southern taiga of Western Siberia were studied. The form differentiation of pine by color of male cones is shown not to be dependent on the size of pollen grains. The reduction in the linear sizes of microstrobiles and the number of microsporophylls in pine trees in oligotrophic bogs is considered as an adaptations, which provide the development of male generative structures in conditions of trophic limitation.
