VEGETATIVE REPRODUCTION OF POPLAR BASHKIR PYRAMIDAL BEREZIN-LEVASHOV (POPULUS NIGRA L. × P. NIGRA F. ITALICA DUROI) IN THE CONDITIONS OF THE EDUCATIONAL EXPERIMENTAL FARM OF UFA LEMONARIUM
This article examines the vegetative reproduction of a hybrid poplar of the Bashkir selection by winter stem cuttings in a greenhouse with the use of growth and root formation stimulants. The issue of obtaining in the required volumes of standard planting material of ornamental plants is currently very relevant, especially for the Bashkir pyramidal poplar, for which vegetative reproduction is the only possible option, since there are only male specimens of this hybrid, as at the stage of selection were destroyed females. To obtain exact copies of the mother plant, cuttings are the best way of propagation. The article discusses the use of 3 growth stimulants and control (without stimulants), describes the biometric characteristics of the obtained saplings, characterizes the length of the root system, the time for rooting, survival of rooted saplings. Identified the most effective preparations and conditions for growing saplings. The conducted research makes it possible to develop practical recommendations for the cultivation of rooted cuttings of the Bashkir pyramidal poplar in a greenhouse.
