Abstract

Introduction. Over the past ten years, there has been a deterioration in the state of recreational planting, urban ecosystems, protective forests and forest-agrarian landscapes, which leads to a violation of the ecological balance in the vast territories of the country. At the same time, the degradation of the soil cover (water regime) is observed, natural ecological systems are being destroyed due to climate change, and there is a danger of extinction of many animal species. Replenishment of the assortment of trees and shrubs is of significant practical importance for agro- and urban landscapes of the dry-steppe, semi-desert regions of the Volgograd region and the Lower Volga region. Special attention of the scientific community is currently focused on the development of electro physical methods of influencing plant seeds, including tree species, in order to obtain stronger and higher-quality seedlings.

Object. The seeds of Crimean pine (Pinus nigra.L), widely distributed in various types of protective forest plantations of the Southern Federal District, and were chosen as the object of research.

Materials and methods. In the laboratory of the Volgograd State Agrarian University, a prototype of an installation for the study of seeds treated in a high-voltage alternating current electric field was assembled, consisting of an industrially manufactured SCAT-70 apparatus, two plate electrodes placed in an experimental cell. To study the response of woody plants to the modes of electro physical exposure, experiments were laid, according to which the impact of a high-voltage alternating electric field on the qualitative indicators of the development of seedlings was assessed.

Results and discussion. The field experimental studies performed to determine the qualitative indicators of the development of seedlings of tree species and the change in their morphometry during electrical stimulation confirm the hypothesis of a positive effect of the alternating current electric field. Positive results have been revealed, which significantly increase the development of the root system and the plant itself by accelerating the course of biological processes and releasing additional energy for plant growth.

Conclusions. Based on the research during the field experience in the nursery of the Nizhnevolzhskaya Station for the selection of woody Plants of the Federal Research Center of Agroecology of the Russian Academy of Sciences, the following conclusions can be drawn: – The effect of a high-voltage AC electric field on the seeds of Crimean pine has a generally positive effect by increasing the quality indicators exceeding the standard methods of intensive agricultural techniques for growing planting material; – Seeds that have undergone electrical stimulation above the value of the electric field strength of 5.0 kV / cm sharply worsen the development of the plant and the percentage of healthy seedlings.
