ns 4.2.2. Comparison of parameters of diameter structure model between clones Usporedba parametara modela debljinske strukture između klonova Depending on plantation age, the results of the analy-structure model showed the decreasing trend and the misis of variance test showed mostly significant differen-nimal value occurred in the eighth year, and the predoces between the parameters of Weibull diameter minantly increasing trend started in the twelfth year. In structure model (Tables 6, 7 and 8). In the initial period, the eighth year, there were no significant differences F-ratio of all three parameters of theWeibull diameter between parameter “c”of the diameter structure mo del, Table 6 Mean values of location parameter (a) of theWeibull diameter structure model and the results of the analysis of variance test and LSD test at the risk level of 0.05 of study clones per years of measurement.
