Investigation of the spruce stand radiation regime
1998
Tomaskova, K. (Mendelova Zemedelska a Lesnicka Univ., Brno (Czech Republic). Lesnicka a Drevarska Fakulta)
Radiation regime is the important part of the energy flow through the stand structure. The goal of the radiation regime studies in the forest stand is to create and develop the technology for radiation measurements and to estimate the impacts of stand density on the radiation regime. The experiment is carried out the Experimental research site Bily Kriz in the Moravian - Silesian Beskydy Mts. with a Norway spruce monocultural stand. Intensities of photosynthetic active radiation, global radiation and intensities of incident and transmitted photosynthetic active radiations through the stand were measured.
Afficher plus [+] Moins [-]Synusiae of cambioxylophages of subdominant Norway spruce trees stressed by root-fungal pathogens

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.
