Induction of rhizogenesis in triploid aspen (populus tremula l.) in vitro

Triploid aspen (Populus tremula L.) is a valuable woody species. Triploid aspen is a valuable tree species. Unlike diploid forms of aspen, it is not subject to core rot, has rapid growth and forms a large phytomass. Plantation cultivation of triploid aspen is important for enriching the gene pool of the main forestforming tree species in the Republic of Bashkortostan and obtaining high-quality wood raw materials. Valuable properties and qualities of tree species are most fully transmitted in the offspring during their vegetative cultivation, especially during microclonal reproduction. The article presents methodological aspects of rooting aspen triploid on artificial nutrient media. The methodology has been worked out and the optimal composition of the nutrient medium for rooting micro-plants of aspen triploid under in vitro conditions has been developed.
