Savchenko Y. Stabilization of obtaining the planting material of Scots pine (Pinus sylvestris L.) with the actions of phytostimulating activity medicine

The thesis is devoted to actual scientific problem, including the investigation of the physiological basis of a medicine with varied phytostimulating activity to stabilize receiving planting material of Scots pine. The principal possibility of obtaining high quality and biologically resistant planting material of Scots pine plants with phytostimulating medicine activity (growth of biostimulants and micronutrients) are shown. Growth activity in laboratory and field conditions in different model systems were studied and technological methods to increase sowing qualities of seeds and planting material and morphometric parameters of Scots pine were developed. A comprehensive study of the physiological activity of growth was carried out by biostimulator "Stympo". Its 23 impact on growth processes of planting material Scots pine were studied. The possibility of using biostimulator "Regoplant" as a regulator of root activity and technology of its application to improve the survival rate and biometric parameters Scots pine seedlings were shown. For the first time it was experimentally confirmed that multi-micronutrient "Avatar-1" has the properties of growth regulator of the planting material of Scots pine. High efficiency of medicine with phytostimulating activity to enhance physiological and biochemical processes of planting material Scots pine were scientifically substantiated and experimentally proved. The stimulatory effect of the medicine "Stympo" causes the improvement of the functioning of endogenous regulation of physiological processes, including the growth of the merger of water, phenolic compounds and peroxidase enzymes and reducement of the amount of water shortages and intensity of the transpiration of Scots pine seedlings compared to control. The highly effective approaches for getting high-quality planting material of Scots pine, which includes pre-soaking seeds and root plants Scots pine seedlings in aqueous solutions of phytostimulating medicines were offered. The investigated range of physiological responses of planting material of Scots pine by using phytostimulating substances could be used to evaluate the effectiveness of new drugs of biological growth regulators on natural raw materials. The effective methods of increasing the quantity and quality of formed planting material of Scots pine that do not require considerable expenses and changes in the technological process of cultivation were developed.
