Vladimir Godin


Sexual structure of populations 47 dioecious Potentilla bifurca in the steppe, forest-steppe and alpine zones in the six provinces of the Altai-Sayan mountain region studied. Sexual spectrum allocated two types of populations: with an equal sex ratio and forms with a predominance of females. Polycentric species P. bifurca, unisexual ramet within one intricate individuals, significant predominance of vegetative propagation of seed, high rate of proliferation specifics sexual structure of populations of the species is determined.
