Increased market demand for high-quality Nordmann fir (Abies nordmanniana) Christmas trees, achieving reduced production costs and improved pest resistance, necessitates the establishment of efficient mass micropropagation platforms for the species.

Conifer tree species belonging to Abies are notoriously difficult to propagate vegetatively due to aging of material, slow rooting, and persistent plagiotropism in rooted cuttings. We produced orthotropic shoots by reiteration from strongly pruned tr

Pedigree reconstruction via DNA markers and subsequent quantitative genetic analyses in production stands of trees is an alternative to traditional forest tree breeding. The method requires variable DNA markers; preferably cost-efficient to genotype.

Provenance variation in Christmas tree characteristics in subalpine fir (Abies lasiocarpa) planted in Denmark and Iceland

Autor: Ole K. Hansen, Brynjar Skúlason, Ulrik Bräuner Nielsen

Publikováno v: Scandinavian Journal of Forest Research. 33:222-232

A field test with 26 provenances of subalpine fir and corkbark fir was established at three sites in Denmark and one site in Iceland in 1999. Survival, growth and Christmas tree quality were assess...

Publikováno v: Scandinavian Journal of Forest Research. 32:366-375

Noble fir is the leading Christmas tree produced in the US Pacific Northwest (PNW). This study is based on evaluations of 24,721 trees collected from five native collection regions in Oregon and Washington plus imported seed from Denmark. The major c
