Comparison of Norway spruce (Picea abies [L.] Karst.), Scots pine (Pinus sylvestris L.) and European larch (Larix decidua Mill.) stem shape by means of geometrical methods

Popis výsledku v původním jazyce

This article deals with stem comparison of three coniferous tree species: Norway spruce, Scots pine and European larch. Stem is investigated by means of geometrical methods. Simplified Bookstein coordinates (stem shape diameters) were used as well as Procrustes coordinates for variability investigation. Material, originated from the Czech and Slovak territories, involved in total 3 346 spruce stems, 3 082 pine stems and 1 403 larch stems. Accordance of mean stem vectors was assessed by means of Hotelling?s two-sample test. For stem shape diameters and Procrustes tangent coordinates, the variability was examined, using the method of principal components analysis. Three most important principal components were diagrammatised and described. Also the relationship between the stem shape and its size was investigated, and inflection points of morphological stem curve were described for all three tree species.
