Comparative analysis of the efficiency of root formation of cuttings in aeroponic and hydroponic systems

Cutting is the fastest way of plants reproduction, which implies that rooted shoots reach the size of an adult plant in a short period of time. The sim- plest and most common method of cutting is rooting cuttings in water or in the ground; however, there are environmental technologies for growing plants - in hydroponic and aeroponic units using artifi- cial/natural nutrient solutions. The aim of the re- search was to conduct a comparative analysis of the effectiveness of root formation process of tree and shrub vegetation on the example of Thújaoccidentális, L and Syringajosikaea, J grown in natural nutrient solution in hydroponic and aeroponic units. The research was conducted at the Department of Landscape Architecture and Arti- ficial Forests of Northern (Arctic) Federal Universitynamed after M.V. Lomonosov (Arkhangelsk). The cuttings of arborvitae and lilac were rooted in aeroponic and hydroponic units in laboratory condi- tions during 45 days. "Gumistar”, natural 2 % or- ganic solution, was used as a nutrient solution...
