Testing of Douglas-fir provenance seedlings in Serbia

Abstract

The genetic diversity of Douglas-fir provenances was compared in the early stage of seedlings in nursery conditions. This paper presents the dependence of Douglas-fir diameter on geographic characteristics of the provenance in the juvenile stage in Serbia. The original seeds of fourteen provenances were collected from the part of the natural distribution area in Canada. The seedlings were produced in the Institute of Forestry nursery, where all measurements were also done and analyzed. There is a positive correlation between longitude and diameter and this correlation is statistically significant. There is a negative correlation between altitude and diameter, and this correlation is statistically significant. Douglas-fir, as the most productive species in its natural range in Canada, should show the highest expectance for reforestation in Serbia, with well-selected provenances.
