Особливості розвитку ехінацеї пурпурової (Echinacea purpurea (L.) Moench ) в багатокомпонентних рослинних угрупованнях Юрченко, І.Т.; Кохан, Т.П.; Купенко, Н.П.; Журавель, Т.А. Results of investigations of Echinacea purpurea (L.) Moench development peculiarities in modelled multicomponent plant communities are preseted in the article. The investigations have been conducted with the objective of a search for optimum plant communities composition in which this species would be able to reach phytocenotic optimum. It has been determined that Echinacea purpurea growth is positively influenced by leguminous species Medicago sativa L. ‘Veselopodolyanskaya 11‘, Galega officinalis L. in three-specific variant. The content of graminoid species (Agropyron pectinatum (Bieb.) Beauv.) in plant community as competitors for environmental resurses inhibits growth of Echinacea purpurea (L.) Moench plants.

Оценка современного состояния популяции Aconitum rogoviczii Wissjul. в национальном природном парке «Святые Горы» Шпилевая, Н.В. Adaptive reactions of the population of protected Aconitum rogoviczii species to anthropogenic changes within the bounds of “Holy Mountains” national natural park have been investigated. Basic demographic - and - coenotic parameters of the species, such as density and age structure have been studied. The research of phenotypical variability has been conducted on the basis of some morphometric features of the given species individuals. The present-day state of Aconitum rogoviczii population and its development prospects have been estimated.

Физиологические особенности базидиомицетов - разрушителей хвойной древесины Шевкопляс, В.П.; Вовк, Н.В.; Мезенцева, Т.В.; Бойко, М.И. In this work the physiologic features and ligninolitic activity of the basidiomycetes that are the destroyers of the pinewoods have been studied. It is established that the fungi L. cyathiformis IX, when is grown for 30 days in the nutrient medium of Czapek’s (control) has a most physiological activity. It is shown that the organic addition in the mineral nutrient medium of Czapek’s decreases an ability of fungi to accumulate the biomass (0,43-0,42 mg/ml), but all fungi studied had different ability to produce extracelluar proteins in the nutrient medium. The spectrophotometry method to define ligninolitic activity of the studied basidiomycetes has been used. It is shown that the increase of the optical density (D380 D440) in the cultural liquid against control nutrient medium presupposes that lignolitic ferments in the CL are available. But the ligninolitic activity of conifer affecting is determined not only by their appertaining to certain species but also depends upon the nature of the organic addition. A new approach for determining quantitative characteristic of ligninolitic activity of basidiomicetes has been proposed.
