Branching pattern in the ontogenesis of Nepeta manchuriensis (Lamiaceae) individuals

Abstract

The features development and branching pattern of N. manchuriensis individuals in the conditions of the Far East were studied. It is established that ontogeny consists the ontogeny of the seed individual and the private ontogeny of the ramet. The seed individual pass through the following stages of development: primary shoot-main axis-primary bush-clump-system of partial shoots; ramet: system of partial shoots. Individuals develop according to the sympodial long shooted model of the shoot formation. Basis structure the whole plant is a consistent development of dicyclic rhizomatous-long shoots. The branching pattern is determined by the functioning the buds the first annual growth of the dicyclic shoot. The mechanism of branching occurs according to dychasial type. The geophilic parts of the shoots form a rhizome.
