INVASIVE CYCLE AND ASSESSMENT OF THE DEPTH OF INVASION OF REPRESENTATIVES OF DENDROFLORA OF UKRAINE IN THE SOME ECOSYSTEMS BY EUROPEAN MISTLETOE (VÍSCUM ÁLBUM L.)

Research is related to the biology and ecology of white mistletoe (Víscum álbum L.), with an analysis its impact on dendroflora natural artificial ecosystems. The sequence stages invasive cycle mistletoe, starting from stage infection, intensity invasion (the degree spread in crown), suppression host trees, their death biodegradation, as well mechanism these processes. These have different durations species. A comparison full infection for those species that are most often infected Polissya, Eastern Podillya coastal areas right bank Dnieper. sensitive were following: Populus nigra L., balsamifera Tilia cordata Mill, Salix babylonica fragilis Juglans L. cinerea Sorbus aucuparia Betula pendula Roth , Acer saccharum Marshall, saccharinum Fraxinus excelsior by also takes into account aforementioned some other species, become particularly threatening today, so it requires finding ways solve this biological environmental problem. However, a number tree can resist spreading even under due mechanisms ensure high resistance, among them pyramidalis Rozier, hybrids poplars, Quércus rúbra L, others. able conditions presence inner relatively resistance parasite, them: hybrids, Prunus avium cerasifera Ehrh. significant outside influence mistletoe. It indicates existing specific barriers which block following adaptation Víscum album populations. concept sensitivity representatives offered. algorithm determining tention album, processes suppression, subsequent biodegradation affected trees optimized. classification nature interaction carried out.
