Abstract

The progress of ontogenesis is analyzed in four members of the genus Trfolium, Lupinaster section and it is shown that the ecological conditions have a guiding influence on the course of individual development of the species. The most important among them are: soil mechanical composition, distance from the seashore, regime and intensity of moistening. Six variants of the ontogenesis, having two subvariants for three of them, were allocated for the members of the section. The initial stages of the ontogenesis are similar, but the main differences begin to manifest from the virginal age. Evolutionary transformation within the section are expressed in reduced leaflets of compound leaves, weakened functioning of the main root, rhizome development, and the transition of perennial forms to vegetative biennials.
