Morphogenesis of growth processes of Ligustrum L. in the Botanical Garden of the Ural Branch of the Russian Academy of Sciences in Yekaterinburg

Abstract

The article is devoted to the study of the duration of phenophases of two species - Ligustrum vulgare L. and Ligustrum ibota Siebold et Zucc. in the collection of the Botanical Garden of the Ural Russian Academy of Sciences. The patterns of growth of annual vegetative shoots have been established. The average duration of growth and development of branching shoots ranges from 112 days in Ligustrum ibota to 126 days in Ligustrum vulgare. Features of the mechanisms of apical growth of vegetative shoots are manifested in the form of differences and similarities in growth rhythms. Apical growth has similar curves of seasonal dynamics in shape and is characterized by synchrony in Ligustrum vulgare, which may indicate the similarity of their mechanisms in different shoots. There are also specific characteristics in the growth rate of privets; of the two species, Ligustrum vulgare is characterized by a high rate of apical and radial growth.
