Osipov M. The Forest features of hawthorn onecarpellary (Crataegus monogyna Jacq.) and use of it in the conditions of Right-bank Forest-steppe of Ukraine.

Object of research - forest plantations Right-Bank Forest-Steppe of Ukraine with participation of onecarpellary hawthorn (Crataegus monogyna Jacq.). Purpose - to find out properties of hawthorn onecarpellary as a component of biocenosis, feature of reproduction and growing, and to ground introduction of him to the forest planting of the different setting. Research Methods - Forest-taksatsiyni, typological and soil, field, laboratory, shipping, mathematical and statistical. Scientific novelty - the first time in terms of Right-Bank Forest-Steppe Ukraine studied hawthorn onecarpellary relation to environmental factors and determined limits its spread within the experimental region, especially the passage of phenological phases and fruiting, depending on growth conditions; investigated the structure of the root system hawthorn onecarpellary different origin, the features and its distribution in different environmental conditions. Established that the majority (60-70%) of physiologically active roots Hawthorn onecarpellary placed at a depth of 40 cm and the root system does not affect the distribution of the roots of oak and ash. The practical significance - in a study describing the biological, ecological, silvicultural features Hawthorn onecarpellary and its impact on the main lisotvirni species, allowing efficient use Hawthorn in growing forest plantations and lisomelioratsiyi on land not suitable for agricultural use. Area of application: forestry.
