Abstract
The populations structure of Aconitum krylovii Steinb. and Aconitum septentrionale Koell was studied in the pine forest in Altai mountains. Cenopopulations of both species is normal, young, with ontogenetic spectrum left -side type. Density in A. krylovii cenopopulations loci varies from 5.1 to 9.4 adults per 1 sq. m, increasing in the middle part of the slope. The sprouts density is insignifi cant. The self-maintenance of the cenopopulation is mainly vegetative. Density in A. septentrionale cenopopulations loci is low, 2.3-2.6 adults per 1 sq. m, the seedage is suppressed. The more favorable conditions for the species is at the bottom of the slope.
