Microclonal propagation of tree and shrubbery species

Cloning of the tree and shrubbery species is carried out in conditions of axenic culture in vitro by method of micro leaf-cutting. The method allows to get the vegetative breeding being the exact copy of the parent plant. It is most expedient to use microcloning for breeding of valuable forms of tree and shrub species distinguished by decorative features, resistance to pests and diseases, or outstanding rate of growth. Micropropagation of Karelian birch varieties and triploid aspen resistant to heart rot can serve as the example of successful application of this method.

Also it is possible to obtain new valuable properties not found in the nature which is realized by mutagenic effecting on plant cells that are cultivated in crops in vitro.
