ABSTRACT: This paper deals with a specific type of homogeneous beechwood called Fageta paupera. The aim is to acquire information about the heterogeneity of soil environment. As a material we used 20 research plots of semi-natural European beech stands, where the sampling of soil profile and the observation of floristic conditions were realized. Laboratory assessment of soil samples was focused on physicochemical and chemical properties of soil: pH/CaCl2, K+, Ca2+, Mg2+, CEC (T, S, V), Cox, Nt, C/N, C-FA, C-HA, C-CHL, C-HA/FA. Data processing was done with the aim to discover...

ABSTRACT: The effects of the within-trial spatial variation of environmental factors on phenotypic traits were studied in the Slovak plot of the international beech provenance trial coordinated by BFH Grosshansdorf with 32 provenances, established under a randomized complete block design with three adjacent blocks. Five indicators of soil properties (soil moisture, bulk density and pH) and microclimate (average daily temperature and temperature amplitude) were assessed at 96 points distributed over a 10 × 10 m grid and their values for the positions of individual trees were estimated by ordinary point kriging. The evaluation of phenotypic variation...

An experiment with seedlings of Alnus viridis was established on a clear-felled tract situated on a summit tableland of the Jizerské hory Mts. (central Europe, Czech Republic) at an altitude of 980 m a.s.l. The aims of the experiment were (i) to evaluate the response of A. viridis to the application of a basic mixture containing crushed limestone and amphibolite and (ii) to assess the growth potential of the species in a poor acidic site under climatically harsh conditions. Alnus viridis showed a good growth performance and survival rate, its initial response to fertilization was positive. The height growth and expansion...

J. For. Sci., 2011, 57(5):210-218 | DOI: 10.17221/17/2010-JFS
The study was aimed at the area of the Krušné hory Mts. with stands of substitute species, soils disturbed by long-term acidification and affected repeatedly by aerial ameliorative liming. Ten species of earthworms were recorded. The highest abundance was shown by earthworms of Dendrobaena attemsi, Dendrobaena octaedra and Dendrobaena vejdovskyi, which are considered to be acidotolerant being, however, monitored in the high and balanced abundance at pH 2.8-6.2. Ubiquitous species developed in soils of markedly lower pH, viz. Lumbricus rubellus (2.8-5.6), Aporrectodea caliginosa (3.1-5.5), and Octolasion...

Conversion of coniferous monocultures to more stable mixed stands is one of the crucial tasks of present forestry in the Czech Republic. One of the factors hampering this process is the activity of small rodents that can cause severe damage to young plantations in winter. Little knowledge is still available of the ecology of small mammals in the forest environment and of the factors influencing their distribution and extent of damage. In order to acquire relevant information on rodent impacts on forest regeneration, we mapped the cumulated damage to forest plantations in 13 regions within the Czech Republic in 2007 and 2008. We checked 19,650 trees...
Preliminary study on phloemogenesis in Norway spruce: influence of age and selected environmental factors

The process of phloem formation in Norway spruce (Picea abies [L.] Karst.) was analysed during the growing season 2009 in Rájec-Němčice locality (Czech Republic). The research series consisted of research plots with 34 and 105 years old spruce monocultures. The formation of phloem cells was determined by the examination of small increment cores taken once a week. Cross-sections of tissues were studied under a light microscope. Cambium activation was observed on 9 April both in young and old trees. On the same date the first newly formed cells of early phloem were observed in old trees but in young trees one week later. Although the time of...
