Streszczenie:
The discriminant analysis method was used for the purpose of allocation trees to Kraft classes. The Scots pine trees were used to determine discriminant functions. Only traits which can be measured on the standing trees were taken into consideration. They included height, breast height diameter inside and without bark, basal area, double bark thickness, 5 and 10 years increment in breast, height diameter, tree slenderness. Some sets of uncorrelated traits were taken into account to select the better discriminant functions guided by the minimum of erroneous classification probability. The discriminant model based on the height, 10-years increment at the breast high diameter, basal area and slenderness, has proven to be the best for grouping the trees.
