Pupils of the school forestry from Bugulma visited the Forest Selection and Seed Center in the Sabinskiy district, which is considered to be the largest in Europe. The children got acquainted with the latest equipment of the complex, which allows growing planting material with a closed root system, then inspected the dendrological garden and a greenhouse where tropical and subtropical plants grow. Children were also shown aspen with genetically improved properties. Their uniqueness lies in the fact that these trees grow twice as fast as ordinary aspens, due to the fact that they have not two but three chromosomes. New species of aspens are already planted in Tatarstan.
