Ojców birch (Betula oycoviensis Besser) is a rare and critically endangered taxon of the genus Betula. Its distribution is limited to few countries in Europe. In the Czech Republic, this taxon, characterized by typical shrubby habitus, has been found in fewer than 70 tree individuals, prevailingly in the studied locality Volyně, West Bohemia. This study was focused on the germinative capacity and germinative energy of this taxon, as it is an important indicator of possible regeneration of the trees in nature and for conservation. Non-stratified seeds (2 200 pcs) and stratified ones (2 200 pcs) were compared to each other and in relation...

Two-years-old Sequoia sempervirens seedlings were foliar sprayed once and twice with chlorocholine chloride (CCC) at 0, 100, 500, 1 000, 1 500 and 2 000 mg.l-1. The purpose was to investigate the effect of CCC on the growth and photosynthetic activity of S. sempervirens seedlings under natural cooling and drought in autumn and winter. The findings showed that the increments of plant height and crown diameter were significantly decreased with the increase of chlorocholine chloride concentration, and the increment of root collar diameter, net photosynthetic rate, actual photochemical quantum yield and photosynthetic electron...

Identification of ectomycorrhizal (ECM) fungi in different ecosystems has major significance. In this research, to identity ECM fungi, we used two methods including the morphological method and the molecular method that is more precise. Basidiocarp collection of fungi associated with oak tree (Quercus brantii Lindl.) roots was carried out in the spring season 2016 and was identified by morphological and molecular methods. We also checked macroscopic and microscopic features and measured each structure using BioloMICS Measures software. To verify the morphological identification, the internal transcribed spacer (ITS) region was amplified by...

The state of ecological balance of cities is determined by the analysis of the qualitative composition of green space. The lack of green space inventory in small towns in the Kyiv region has prompted the use of express analysis provided by the EOS Land Viewer platform, which allows obtaining an instantaneous distribution of the urban and suburban territories by a number of vegetative indices and in recent years - by scene classification. The purpose of the study is to determine the current state and dynamics of the ratio of vegetation and built-up cover of the territories of small towns in Kyiv region with establishing the rating of towns by eco-balance...
