It has been established that the modern seed potential, analysis of the anticipated yield and approximate harvesting amount of relict tree seeds in the western region of Ukraine make it possible to harvest a significant amount of seeds annually and grow enough planting stock to fully meet the reintroduction needs of the species. A set of studies had been conducted to determine the sowing qualities of seeds - purity, good quality, humidity, weight of 1000 seeds. The cultivation of planting stock of common yew is rational to practice mainly in the open ground. The technology of growing seedlings in the open ground involves the following stages: high-quality continuous tillage, autumn or spring sowing, weed control, loosening of excessively compacted substrate between rows. The following features of phytomass distribution of organs of 1-8-year-old yew seedlings have been established. The smallest part of the weight of the seedlings is made up by branches (1.72-15.04%). The use of 50% NaOH solution and 40% H2SO4 solution, potassium humate "GVK-45" produced by LLC "PARK" and biostimulators "Zircon" and "Epin-extra" for pre-sowing treatment of stratified seeds (heeled in for a year in the soil mixture after six months of storage in the refrigerator at a temperature of + 2… −2 ºC) and freshly harvested, prepared for stratification seeds, showed different effectiveness of the described plant growth regulators. The use of NaOH and H2SO4 solutions, potassium humate "GVK-45" and biostimulants "Zircon" and "Epin-extra" proved to be the most effective for pre-sowing preparation of common yew seeds. Studies to test the effect of stimulants "Kornevin" and NAA with three different concentrations on the process of rooting in the autovegetative propagation of yew showed their different productivity. The best results were obtained when the cuttings of Taxus baccata L. (typical form) were processed with "Kornevin" - 66% root-taking. The results of the study of reproduction of valuable genotypes of common yew by microclonal method allowed us to establish the optimal scheme of using this modern and promising method: initiation - on a nutrient medium LM + 2.4-D (0.2 mg / l) + BAP (0.1 mg / l); accumulation - LM + 2.4-D (0.2 mg / l) + BAP (0.1 mg / l) + (0.5 mg / l); rooting - 1/2 MS + 2.4-D (0.2 mg / l) + NAA (0.5 mg / l); adaptation - in ready-made factory-produced peat pellets. The economic efficiency of growing 1-5-year-old common yew seedlings in the open and protected ground and 1-5-year-old transplanted cuttings of the species grown in the protected ground (greenhouses and hothouses) and cuttings with a root-ball tree system has been studied. The above calculations confirm the economic efficiency of growing common yew. At the same time the least expensive is the cultivation of the planting stock by seed. The use of seeds, collected on one’s own, reduces the cost of cultivation by 7-10%. The obtained results of determining the content of chlorophylls and carotenoid pigments in fir-needles of different age of the planting stock of common yew grown in the open ground and in greenhouses in the western regions of Ukraine indicate the high adaptability of young common yew plants in the conditions of Western Ukraine. Perspective and top-priority areas of use of common yew in today's context are landscaping and landscape architecture and forest cultivation. When using yew in landscaping and landscape architecture, introducing the species into various types and kinds of greenery, especially in large cities, would be perspective. It is not recommended to plant yew around and near playgrounds, kindergartens and schools due to the high toxicity of fir-needles, bark and seeds. The available experience of growing common yew in artificial forest plantations of the studied region shows that the introduction of a rare species in the composition of artificial forest plantations in the future is possible and necessary, if there is a sufficient amount of planting stock within the artificial reforestation. At the same time, it is necessary to use planting as a method of creating artificial forest plantations, as the regeneration of common yew under the forest trees by sowing proved the futility of using this method. For the successful creation of highly productive and biologically stable forest crops involving common yew, it is necessary to begin the works on the formation of a permanent forest seed base. In the process of forest crops development involving common yew, one need to use seedlings of 5-6 years of age with an above-ground part of at least 25-30 cm. Agrotechnical tending of common yew forest crops should be done for at least 4-5 years at the intervals of 4-5 tending operations per the vegetative cycle. When doing forestry tending, one should ensure systematic exposure of yew plants to light. Clean and mixed common yew forest crops should be planted in areas up to 1 ha, mixed forest crops should be planted in larger areas.
