RESULTS ON PINE TREE HEIGHT INCREMENT USING THE GIERUSZYńSKI AND MEIXNER FORMULAS K. Kaźmierczak Department of Forest Management, Poznan University of Life Sciences, Wojska Polskiego 71c, 60-625 Poznań, Poland, e-mail: kasiakdendro@wp.pl |
This paper presents the results of investigations into the effect of the age of trees and length of growth period on the accuracy of determination of periodical tree height increments using ten formulas. The experimental material comprised the results of analyses of 200 pine-tree stems which were selected from eight consecutive sub-age classes, from IIa to Vb. All stands from which sample trees were collected were growing in conditions of fresh mixed coniferous forest. The same calendar growth period (1989-1999) was adopted for each tree, in order to eliminate the effect of additional factors such as site, climate and meteorology on the height increment.
