Low-frequency electromagnetic field influence on anatomical stem structure of scots pine (Pinus sylvestris L.) and red oak (Quercus rubra L.) annual seedings

The study determines the influence of a low-frequency electromagnetic field on the anatomical stem structure of the annual seedlings of Scots pine (Pinus sylvestris L.) with a root-balled system, carried out in the nursery of the Ustyansky forest seed breeding center of the Arkhangelsk region, and annual seedlings of red oak (Quercus rubra L. ) carried out in the forest nursery of the Donskoy forestry of the Forestry Department of the Lipetsk region, when planting in open ground with the introduction of a hydrogel. Experimental samples of annual seedlings of Scots pine and red oak were treated with a low-frequency electromagnetic field using the patented POSEP technology (pre-sowing treatment of seeds and seedlings with an electromagnetic field) using the «Rost-Active» device (low-frequency generator). Untreated seedlings served as control. Conducted in the laboratory of the Department of Forest Plantations, Breeding and Dendrology of the BMSTU (Mytishchi branch), histometric analyzes of experimental and control samples of annual seedlings of Scots pine and red oak showed a positive effect of a low-frequency electromagnetic field on the anatomical characteristics of their stems.
