Ontogeny of Dianthus andrzejowskianus (Zapal.) Kulcz. in the conditions of the Bashkir Pre-Ural

Abstract

The article is devoted to the results of the introduction study of Dianthus andrzejowskianus (Zapal.) Kulcz. on the basis of the South-Ural Botanical Garden-Institute of Ufa Federal Research Centre of RAS. Data on the ontogenesis of this species are provided. Three age periods (latent, pregenerative and generative) and 6 ontogenetic states (seedlings, juvenile, immature, virginal, young and middle-aged generative states) are described. Indicator signs of age-related conditions are: for seedlings - the presence of a thin germ root, two oval-shaped cotyledons; for juvenile individuals - the appearance of the first true leaves; for immature individuals - the transition of plants to sympodial growth and the growth of the root system. In the virginal state, the vegetative sphere increases, the plant acquires the features of adults. Young generative plants have few reproductive shoots. The middle-aged generative state is characterized by the most powerfully developed vegetative and reproductive spheres.
