Morphological study of Echinacea purpurea (L.) species back in culture at the agrobiological station of the State University of Moldova

Abstract

In this paper are the results of studying of the morphological structure of Echinacea purpurea species cultivated for two years in indigenous bioecological conditions. In this period of time was analyzed biomass accumulation of different plant parts in different stages of vegetation. The results showed that the dynamics of biomass accumulation in all three parts of the plant has increased capacity as well as the number of flowering shoots, both in the first year of cultivation and in year two. This proves about an increased adaptability to indigenous bioecological condition.

The morphological study of Echinacea purpurea L. plants grown under bioecological conditions of the agrobological station of the State University of Moldova: highlighting the morphological structures of Echinacea purpurea plants grown in bioecological conditions in the first year of vegetation; highlighting the morphological structure of Echinacea purpurea plants grown in bioecological conditions in the second year of vegetation; the biological observations during the ontogeny period were carried out according to the classical methods specific to perennial plants with a bushy aspect proposed by which provides for E. purpurea 3 variants of the realization of the ontogenetic program: the virginal stage, the juvenile and immature stage, the generative period.
