The aim of this paper was to test the Rotfinder® device which use the method of measuring electrical resistances of the wood. Research was conducted in the north of the Eastern Carpathians, in four Norway spruce plots. A total of 1046 healthy standing trees (according with visual inspection) were analyzed. Between 5% and 16% of trees were affected by root rot, the highest values being recorded in the first 5 classes indicated by the Rotfinder ® device. The relationship between the value indicated by the Rotfinder® device and the proportion occupied by the root rot in the cross-section of the Norway spruce trees is given by a logarithmic equation. The correlation is very strong and very significant (r = 0.956***). The correlation between the value indicated by the Rotfinder® and the proportion occupied by the root rot in the cross-section have a considerable practical importance because it is possible to estimate the proportion of root rot in the cross-sectional area for different forest areas. |
