Most of the h/DBH ratio variability (75% at age 11 and 81% at age 16 years) can be attributed to the corresponding DBHs (Table 5). The increments of the trees and the linear plantation – Prirast stabala i zasada Tree vitality assessment showed that the trees are very vigorous (best score according to the classification of Mattheck and Breloer, 1994). The good vitality status of the trees and the plantation is confirmed by recorded increments (Table 6). Distribution shapes of diameter and height PAI are different — diameter PAI is slightly skewed to the right and platykurtic while height PAI is skewed to the left and almost mesokurtic. The distribution shapes of basal area and volume PAI’s are very similar and characterised by slight right asymmetry and platykurtic shape.From age 11 to 16 years, h/DBH ratio has an annual average decrease of 2.25, and the range of decrease is 0.68–4.10 (Table 7). The relationship between the trees’ PAI (diameter) and their corresponding diameters at age 11 years is well described by a linear regression model where 50% of the variability |
