Biometrical relationships of volume increment to crown defoliation and other variables of spruce stands in the Oravska Polhora research site [Slovak Republic]
1998
Smelko, S. (Technicka Univ., Zvolen (Slovak Republic). Lesnicka Fakulta)
This contribution deals with the relationship evaluated on the basis of 32 permanent monitoring plots. Tree volume increment as a total "brutto" and also as a pure "netto" change for 1 ha is defined. The first one includes also the influence of felling, mortality and increment ingrowth, second one includes only changes due to the growth process. Relationship of increment to stand variables is investigated bz stepwise regression. A more higher correlation to defoliation was found, less high to age, site index and altitude.

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.
