Within this research we substantiate the importance and relevance of plantation forestry in the context of the forest restoration process and effective use of land resources, intensification of forestry production. The attention was paid to the historical aspects of plantation forestry, when repeated attempts were made to create plantations of fast-growing species, including poplars, both in sparsely forested and industrially developed regions. The main purpose of the research is a preliminary expert assessment of the suitability of the tested poplar cultivars for plantation forestry in conditions of fairly infertile oak site type of the northern part of the Right-Bank Forest-Steppe zone based on features of rooting and growth of cultivars' planted cuttings in test plantations, starting with the phase of engraftment. We indicate that the program tasks research was carried out using the techniques commonly used in forestry and general scientific methods: analysis, synthesis, comparison and generalization of the collected scientific materials. The suitability of some poplar cultivars for cultivation in fairly infertile oak site type is evaluated by means of phytoindication method. We have characterized the features of lignified cuttings' rooting and growth of one year-old planted cuttings of different poplar clones in test forest plantation in conditions of a wet fairly infertile oak site type of the Kyiv Forest-Steppe zone. We have carried out the preliminary expert scientifically based assessment of suitability of certain poplar cultivars of domestic and foreign breeding for the wet fairly infertile oak site type. We have determined that among the experimentally tested poplar cultivars in the conditions of the research region in the phase of engraftment, a better cuttings' rooting process and a more intensive growth of planted cuttings were demonstrated by clones 'Ijzer-5' and 'Ghoy'. Worse rooting was inherent to the clones 'I-214' and 'I- 45/51', and slower growth of one year-old poplar planted cuttings was registered for clones Toropohritski, 'San Giorgio' and 'Blanc de Poitou'. A logical explanation of the revealed features is the specific regards of the mentioned cultivars to the soil fertility and moisture content, which shall be considered on the stage of plants selection for poplar plantations.

The peculiarities of rooting of wooded cuttings and preservation of planted cuttings of different poplars clones of plantations are characterized in the conditions of Chernihiv Polissia. It has been carried out preliminary expert scientifically sound assessment of the suitability of using certain cultivars of poplar among clones of domestic and foreign breeding tested in test cultures for plantations establishment in conditions of wet fairly infertile pine site type and fairly infertile oak site type. It is determined that for establishing of forest plantations in the conditions of wet fairly infertile pine site type it is more efficient to use poplar cuttings of Toropohrytskii clone, and in the conditions of the wet and fairly infertile oak site type besides the mentioned cultivar, the clones 'Blanc de Poitou', 'Serotina' and 'San Giorgio' are better.

Productivity and shoots output of 17 poplar cultivars in plantations with “stump” type of management are characterized. The expediency of their use for biomass production and planting material (cuttings) output were evaluated. The optimum height of mother plant’s stump to ensure the greatest productivity of most cultivars is range of 1.0 to 0.5 m. Cultivars ‘Ghoy’ and ‘I -214’ are appropriate for wood biomass production in the examined region. Cultivars ‘Ghoy’, ‘Marilandika’ and ‘Ijzer-5’ are the most productive for planting material (cuttings) store. [ABSTRACT FROM AUTHOR]

The effect of different doses and methods of fertilization while nutrition in subors conditions of Volyn Polissya on annual poplar growth and changes in the studied parameters during the vegetation season were studied. [ABSTRACT FROM AUTHOR]
