|Study of Growth of Douglas Fir Provenances (Pseudotsuga menziesii (Mirb.) Franco) on Krndija pdf HR EN||243|
|Summary: This study programme covers 12 provenances of Douglas fir (Pseudotsuga douglasiessi (Mirb.) Franco) including 6 from the USA, 3 from British Columbia, 1 from Denmark, 1 from Bulgaria and 1 from Croatia (Table 1). Precise data on origin (Character code: F, I, J, T) were not received for 4 provenances.|
Forest seedlings were produced in the tree-nursery of the Forest Research Institute, Jastrebarsko, in Jiffy containers of 8 cm diameter. The seedlings were transferred to the field as 2 1 year-olds, with the exception of Castle Rock provenance, which was 2 0 years old and planted bare-rooted.
The field experiment was established in the spring of 1969 in a randomized block system in 4 replications. Basic spacing of planting was 2 x 2 m. Douglas fir was planted with spacing of 4 x 4 m, and in between Norway spruce 1 2 years old, was planted.
This paper presents the measurement results from 1978 and 1992. Namely, the 10th and 24th year since the establishment of the experiment. Variance analysis and F test were used for testing the differences between the provenances in view of height and diameter growth. Average provenance values were used in the statistical analysis of data.
According to the results in the field experiment on Krndija, the best results, with regard to survival, growth and increment, were shown for the provenances from Denmark (Hvidbilde) and Bulgaria (Šipka). Our Croatian domestic provenance (Buzet) was better than the average for all provenances.
