A common objective has been to create base material for seed procurement. Introduction objectives differ between countries, but most of them include adaptation and health, yield improvement, volume production and wood quality in some way. (Pseudotsuga menziessi Mirb/Franco) is one of the most important coniferous species in Europe both from an economic and ecological point of view. The provenance experiment of the North-West American conifer Douglas-fir were established in Serbia by the Institute of Forestry to test the genoecological characteristics of the species. Provenance experiment, contains the seed sources covering the central range of this species wich were collected from native area in Canada. The test included, fourteen seed provenances originating from Canada. Plants where produced in the nursery of the Institute, where they were measured. Early results from this provenances testing and growth information from the juvenile age in the nursery indicates that there are significant differences among Douglas -fir plants, what justifies the testing of introduced species by provenance experiment. application/pdf 488077 bytes All rights reserved info:eu-repo/semantics/article
