Systematic and elaborate multidisciplinary research of pedunculate oak and common hornbeam began in the Forest Research Institute in Jastrebarsko in 1991. That led to a development of a method for monitoring deposition in forest ecosystems which is now closely related to the International Co-operative Programme on Assessment and Monitoring of Air Pollution Effects on Forest. Several forest comm...
A series of comparable specimens of hornbeam wood were submitted to pretreatments by white-rot fungi, by alkali alone, or by alkali and oxidizing agents. The pretreatments caused weight loss of wood and modified its physical properties and chemical composition. All pretreatments reduced markedly axial permeability of the test specimens in the wet state (w > FSP). The chemical pretreatments of t...
Background: Wood and bark are important renewable natural resources. Density is an property that used to describe wood quality for a number of end uses. However, density, proportion dimensions vary with age site, as well among within trees. The aim this study was investigate the effect diameter class, vertical position stem on density bark, volume, dry-mass thickness Lebombo ironwood (Androstac...
Abstract Rare domestic tree species are increasingly being viewed as promising alternatives and additions to current main in forests facing climate change. For a feasible management of these rare species, it is, however, necessary know their growth patterns space requirements. This information has been lacking science up now. Our study investigated the basic crown allometries four (European hor...
Studying regeneration processes in oak-dominated forests requires a multi-faceted approach that considers local factors, disturbances, management actions, and tree responses. Our aims were to quantify the carbon water-use responses of saplings evaluate ecological consequences at early phase pedunculate oak-hornbeam forest. We measured plant eco-physiological parameters using an open-chamber IRG...
