Varijabilnost zelene duglazije (Pseudotsuga menziesii Mirb. Franco) u testu provenijencija Goleš-Radalje. = Variability of Douglas fir (Pseudotsuga menziesii Mirb. Franco) in the Goleš-Radalje provenance test
Douglas fir is one of the non-native species that has shown high productivity and good adaptation to the conditions prevailing in Bosnia and Herzegovina. This research aims to determine the ...variability of the morphological properties of height, diameter, and volume per provenances in the Goleš Radalje provenance test near Travnik. The results will be used for the purpose of selecting the best provenance in terms of productivity and quality of wood mass for the production of reproduction material. The research was carried out in the Goleš-Radalje provenance test near Travnik. The test includes ten provenances and was established in the spring of 1972 by planting 4-year-old seedlings (2+2). In 2013, diameters at breast height and heights were measured, and volume was calculated. Data were processed with the SPSS 26.0 program. Descriptive statistics, analysis of variance, and Duncan’s multiple tests were performed for height, diameter at breast height, and volume by provenances. The total average diameter value for all provenances was 31,4 cm, height 25,9 m, and volume 0,78 m3 . Provenance 1029 had the highest average value of diameter at breast height, provenance 1036 highest average height, and provenance 1029 had the highest average volume. Provenance 1091 had the lowest average diameter at breast height, and provenance 1046 had the lowest average height and volume. Variance analysis showed no statistically significant differences among provenances for investigated traits. The obtained results indicate that all provenances of Douglas fir in the provenance test Goleš - Radalje can be used for the introduction of green Douglas fir in habitats that correspond to the conditions of the Goleš - Radalje experimental plot, as well as when raising clonal plantations or seed plantations.
