The paper deals with problems of crowns and of the assimilatory apparatus of Douglas fir. Crowns of two trees aged about 70 years of different coenotic (dominant–subdominant) and production (volume: minimum–maximum) position in a stand were analysed. The trees came from the experimental stand 41D7, Training Forest Enterprise Masaryk Forest Křtiny (altitude 430 m). Differences between Sample tree 1 (subdominant tree – V = 0.44 m3) and Sample tree 2 (dominant tree –V = 2.37 m3) were found in the course of the analysis of height and diameter increment. Sample tree 1 was characterized not only by a shorter crown, both absolutely and relatively (in % of the stem length) but also shorter whorl branches and their lower number. While the crown of Sample tree 1 was created by 28 whorls with 3.5 branches/whorl, Sample tree 2 was created by 37 whorls and 4.5 branches/whorl. A different course was also found in case of needle distribution (g × m–1). A unimodal curve was typical of the dominant tree while the subdominant tree was characterized by an irregular multi-peak curve. Throughout the crown profile, Sample tree 1 showed higher values of foliage index (the proportion of needle DM to skeleton DM) than Sample tree 2. The total biomass of needles in Sample tree 1 and Sample tree 2 was 10.55 and 68.2 kg, respectively. Leaf area index (LAI) in Sample tree 1 amounted to 4.90 m2 × m-2 and that in Sample tree 2 5.26 m2 × m-2.
