4. ZAKLJUČAK - Conclusion 1. Najbolji rezultati u pogledu uspijevanja provenimorskih visina, do 300 m. Provenijencija iz Bugarske, jencija zelene duglazije su polučeni u Istočnoj Slavoniji Šipka, također je među najboljima. Naše domaće prona lokalitetu Durgutovca, zatim u Istri na lokalitetu venijencije »Buzet« i »Delnice« pokazale su prosječne Kontija. Slabiji rezultati registrirani su u okolici Bjelorezultate, odnosno nešto slabije od prosjeka. vara na lokalitetu Slatki potok, a osobito slabi u okolici Karlovca na vrištinama, lokalitet Lokve. 3. Općenito, što se tiče uspijevanja zelene duglazije 2. Među najboljim provenijencijama iz SAD za u Hrvatskoj ona pokazuje intenzivan rast na šumskim područje Hrvatske pokazale su se one iz savezne staništima (Durgutovica, Kontija).

SUMMARY: Research covers nineteen provenances of Douglas Fir (Pseudotsuga menziessi (Mirb.) Franco), namely, twelve provenances from the United States, three provenences from British Columbia, one provenance from Denmark, one provenance from Bulgaria, and two provenances from Croatia (Table 1). No data was received about the geographic background of the provenances Elk River Falls and Melville Black from British Columbia and Castle Rock, Washington and Hvidkilde from Denmark. In the Spring, 1966 sowing was carried aout in seedbeds and in the Spring, 1968 the plants were transplanted into Jiffy containers of 8 cm in size and were left in the nersery for one more year. Experiments in the field were laid out in the Spring, 1969 and 1970. In Croatia, eight field experiments were laid out in different site conditions. This paper represents the results of four experiments (Table 2, Fig. 2). The experiments were established in a randomized block system with four replications. The basic spacing between plants was 2 x 2 m, while the Douglas Fir, due to the small number of plants, was spaced 4 x 4 m, with usually a Spruce tree planted in between, and in the experiment Kontija Austrian Pine. This paper presents the results of measurements taken in 1978, and the latest from 1987; namely taken in the 13th and 22nd year of the total age of the plants. Variance analysis, F test and Duncan test were used for statistical processing of data. On average the best growth registered in the experiment in eastern Slavonia (D), followed by Istria (K), and considerably poorer near Bjelovar (SP) and Karlovac (L). For conditions in Croatia the best provenances are from the Federal State of Washington at approx. 46° of northern width and at up to 300 m above sea level. The domestic provenances »Buzet« (S) and Delnice (P) are somewhat better, or poorer, respectfully, than the average for the experiment. |
