INDUSTRIAL CULTIVATION OF PLANTING MATERIAL OF SELECTED POPLARS IN THE CENTRAL BLACK EARTH REGION
Abstract
The results of stem cuttings’ rootability of poplars belonging to different sections (white, black, balsamic and a group of intersectional hybrids of eupopulus L.) are presented. The yield of stem cuttings at the experimental production root-cuttings’ plantation established in 2020 at the Kulikovsky Forestry Enterprise of the Lipetsk Forestry Department, produced on 1, 2, 3 and 4-year-old roots, is shown. A rank assessment of the reproductive ability of poplars is given and the most productive ones are highlighted. The greatest reproductive ability was noted in black poplars ‘Sacrau-59’ and P. deltoides L., and in intersectional hybrids of eupopulus ‘Versiya’ and ‘E.s.-38’, which are recommended for creating an industrial reproductive base for growing of selectively improved poplar planting material. On 3-4-year-old roots, the yield of stem cuttings of recommended poplars was 100-170 thousand pieces/ha.
