Abstract (English):
The study focuses on cultivating Pseudotsuga menziesii seedlings with a closed root system at the amenity forest of «VNIILGISbiotech» (Voronezh). It reviews prior research on growing Pseudotsuga with this method and highlights its benefits for the species. The research team collected seeds, and sowed them in peat-filled cassettes. Over three months, regular measurements revealed steady seedling growth and detected the presence of secondary growth. The findings demonstrate the effectiveness of the closed root system for cultivating Pseudotsuga menziesii in the Voronezh region.

Keywords:
