Initial stages of ontogenesis of Althaea officinalis L. in the “Kuzbass Botanical Garden”

Abstract

The work was carried out on the grounds of the Kuzbass Botanical Garden. The study material is a perennial, rod-rooted herbaceous plant known as Althaea officinalis L. Included in the Red Book of the Kemerovo Region with status 2 - declining. It has been found that during the first year of life, individuals go through 5 ontogenetic stages: seedling, juvenile, immature, virginile and young generative. The latent, pre-generative and generative periods of A. officinalis are characterised in detail. The forming of the caudex and the growth of the primary semi-rosette monocarpic shoot is described.
