In vitro propagation as one of the promising methods of conservation of species Cotoneaster melanocarpus Fisch. ex. Blytt.

Abstract

Cotoneaster melanocarpus Fischer ex Blytt is rare species and included in Red Books of Russia (8 Regions) and Belarus, it is included in the list of wild rare and endangered plants of the Kostanay Region in Kazakhstan. C. melanocarpus is used as an ornamental, medicinal, honey-bearing plant, but it is difficult to propagate both seed and vegetative methods. Microclonal propagation of plants is a promising method of propagation and conservation of this species, but there are no researches in this direction in the world scientific literature for C. melanocarpus . The article presents the conditions of in vitro propagation for other species of the genus Cotoneaster , studied at different times by scientists from France, Korea, China, Russia and Iraq. It is shown how the application of various types of explants, sterilization modes, nutrient media, plant growth regulators affect on features of the morpho- and rhizogenesis of Cotoneaster in culture in vitro . This review was conducted for the first time and can serve as a basis for the development of a method for microclonal propagation of C. melanocarpus , which will conserve its gene pool and obtain plant material for practical use.
