Ontogenesis peculiarities species of genus Rorippa Scopoli (Cruciferae) in the subzone of the southern taiga

Latent, pregenerative and generative periods in the ontogeny of Rorippa amphibia (L.) Bess., R. palustris (L.) Bess. and R. ×anceps (Wahlenb.) Reichenb. were described. Skipping of a postgenerative stage, and some of ontogenetic states demonstrates the dynamic multiplicity of individual development; while the combination of seed and vegetative reproductions – multiplicity of the ways of reproduction and generation. The ontogeny of R. palustris individuals corresponds to A-type, R. amphibia and R. ×anceps – to G-type, and R. ×anceps – to D-type.
