This article investigates the state of clones of triploid aspen in the conditions of the southern taiga forest region of the European part of Russia. The silvicultural and taxation characteristics of clones with high physical and mechanical qualities of wood in the genetic reserve of triploid aspen in the Kostroma Region.
The results shows higher productivity of triploid clones than ordinary aspen stands and high stability of triploid aspen to stem rot, providing data on the productivity of clones. Until the age of 50 years, the incidence of stem rot is no more than 10% in the number of trees. The authors note the fast growth, good cleaning of trunks from branches, and a high density of wood in comparison with the usual form of aspen.
Using triploid aspen for plantational forest growing in the zone of activity of modern enterprises of the timber industry complex of the Central Federal District of the Russian Federation including on unused agricultural lands is perspective. An accelerated production of elite planting material of triploid aspen is possible with the use of clonal micropropagation. The application of the plant growth regulator Epin-Extra 0.5 mg/l can be considered as a modifying element of the clonal micropropagation technology of triploid aspen.
