Sažetak
Height and diameter breast height (DBH) were analysed for four provenances of Douglas Fir (Cottage Grove, Centralia, Cascadia and Ashland) and differences among them were determined. The experiment was laid out as a Latin square 4x4 with 7x7 seedlings in each repetition. Repeated measures analysis of variance was conducted to analyse the differences in height and girth increments among individual provenances for 1970, 1980, 1990 and 2000. Research results indicated that there is a statistically significant difference in height and DBH for the studied years. There is also a significant difference in height among the provenances as well as an interaction of years x provenance. In the analysis of DBH, the difference among provenances was not statistically significant, nor the interaction with yeart.
