Abstract
The paper presents the results of an experiment on the propagation of aspen clones (Populus tremula L.) of diploid and triploid genotypes resistant to pith rot by methods of microclonal reproduction and their introduction into forestry production in the Republic of Tatarstan. The expediency of using this method for obtaining healthy aspen planting material has been substantiated, and the prospects for the reproduction of clone No. 35 with a triploid genotype have been shown.
Highlights
Aspen (Populus tremula L.) is one of the fastest-growing tree species, and healthy aspen wood is highly valued. It is distributed throughout Russia and is adapted to forest conditions
Studies have shown that healthy aspen has many valuable forestry and economic properties; it can be effectively used as a thermal energy source
Aspen tends to be affected by fungal diseases that cause pith rot of the trunks, which leads to a decrease in the quality of wood [4,5,6]
Summary
Aspen (Populus tremula L.) is one of the fastest-growing tree species, and healthy aspen wood is highly valued. It is distributed throughout Russia and is adapted to forest conditions. This breed is unpretentious and grows on medium-fertile soils, resistant to frost [1]. In the republic, there are highly productive clones resistant to fungal diseases. Today the most important task of foresters is the creation and cultivation of healthy and highly productive aspen plantations [2, 3].
