Synusiae of cambioxylophages of subdominant Norway spruce trees stressed by root-fungal pathogens
1998
Kula, E. (Mendelova Zemedelska a Lesnicka Univ., Brno (Czech Republic). Fakulta Lesnicka a Drevarska) | Zabecki, W.
Some 30 species of cambioxylophages with the dominant position of Pityophthorus pityographus, Polygraphus poligraphus, Pityogenes chalcographus, Molorchus minor and Obrium brunneum were recorded on subdominant trees attacked by Armillaria sp. and Heterobasidion annosum. The stress induced by fungal pathogens on subdominant trees causes unfavourable conditions for the development of Ips typographus and increases attractiveness for P. poligraphus and M. minor. Species of P. chalcographus and P. pityographus response indifferently.
Mostrar más [+] Menos [-]Allometric relationships between stem volume and the biomass of Norway spruce
1998
Pokorny, R. (Akademie Ved, Brno (Czech Republic). Ustav Ekologie Krajiny)
The objectives of this study were (I) to establish allometric relationships between the stem volume and biomass of the stem, branches, leaves and the leaf area, and crown dimensions of individual trees, (II) to determine the relative aboveground biomass distribution, (III) to determine the vertical gradient of the specific leaf area and (IV) to estimate the aboveground stand biomass and the leaf area. Diameter at 0.3m height above ground and height of each tree were measured as the basic biometrical characteristics. The coefficient of the shape of the trunk was found by Huber's method.
