Представлены результаты изучения аллелопатической активности Quercus robur L., Acer platanoides L., Ulmus glabra Huds методом биотестирования. Выявлены различия воздействия аллелохимикатов на прорастание семян и развитие проростков тест-объекта в контролируемых условиях. Показана корреляция концентрации водных вытяжек листового опада и аллелопатического эффекта, оказываемого ими, которая подтверждена анализом функции средней. Here we present the results of studying the allelopathic activity of Quercus robur L., Acer platanoides L., Ulmus glabra Huds by biotesting. We revealed differences in the effect of allelochemicals on seed germination and the development of seedlings of the test object under controlled conditions. The correlation of the concentration of aqueous extracts of leaf litter and the allelopathic effect exerted by them is shown. The mentioned correlation is confirmed by the analysis of the average function.

The history of the forest of Bialowieza is briefly reviewed. The National Park was created in 1923 in the central and apparently least exploited part of the forest. The composition of the forest varies in relation to the nature of the soils. Almost half of the wooded area of the park is occupied by forest composed of Carpinus betulus, Tilia cordata, Quercus robur, Acer platanoides, Ulmus glabra and Picea abies (Querceto-Carpinetum). The structure of this association is illustrated by maps and transects of selected plots. An almost continuous canopy is formed by Carpinus betulus with tall emergent trees of Tilia cordata, Quercus robur and Picea abies. Tilia cordata regenerates freely and there are numerous groups of seedlings, saplings and young trees which are sometimes in gaps but often beneath the main canopy. The origin of the groups is analysed and evidence is presented that those of T. cordata are probably always less than 50 years old. This is in contrast to analyses made by Paczoski (1928a, b, 1930) shortly after the park was established, when trees of T. cordata with trunk diameters less than 0.3-0.4 m were absent. There is now a discontinuity in the distribution of diameter classes in the population. The influence of this change on the structure of the forest is discussed.

Abstract Intense dieback of Fraxinus excelsior L. has been causing rapid changes in advance growth of trees and understory shrub growth of the affected stands. In this study, changes in composition and density of understory were studied in 15 permanent plots (each 235.6 m2), repeatedly sampled in 2005, 2010, and 2015. Within each plot, the number and average height of understory individuals were determined. The successional changes in understory were assessed by Detrended Correspondence Analysis. In total, 11 advance growth and 20 undergrowth species were recorded. A significant increase in the density of understory was observed only in 2015, mainly due to understorey growth of Corylus avellana L., Padus avium Mill., and Lonicera xylosteum L. Regarding advanced growth, the highest density was observed for Ulmus glabra Huds., F. excelsior and Acer platanoides L.; the density of A. platanoides and F. excelsior increased particularly in the period from 2010–2015. The observed successional changes suggested individuality of development of the affected stands according to the composition of the remaining and neighbouring canopy trees.
