Hauck, O. | Palat, M. (Mendelova Zemedelska a Lesnicka Univ., Brno (Czech Republic))
Data necessary for the determination of the proportion of various types of branching in stands under study, their variability within a tree, accuracy of classification of the type of branching, damage to particular types of branching due to breakage and initial age for their reliable recognition were obtained according to method from 1,336 trees situated in 11 trial plots in the region of the Beskids. Statistically significant differences were determined in the diameter and height increments for particular types of branching.

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.
