Abstract

Aspects Related to the Auxology of Forests Affected By Wood Decay

This paper presents a study regarding the auxologic influence exerted by wood decay fungus on Norway spruce forests installed in stands outside the natural area. The method used for quantifying this influence includes calculating the growth coefficient (the relation between the annual radial growth at 1.3 m and at stump level) as a way to measure the biomass deposits along the trunk. The conclusion was that the infected tree increases its radial growth at stump level in order to prevent damages caused by wind and snow, even in the incipient stages of I.

The reaction of Norway spruce trees is related to the auxological stability of the specie in this stands; the indicator has been calculated using spruce's, beech's, and silver fir's variation coefficient of annual radial growth index. We can conclude that coniferous species are less stabile than broadleaved species from the auxology point of view and more resistant to wood decay fungus infection.
