Four provenances of Scotch pine (Pinus sylvestris L.) were tested in Garrett County, Western Maryland. Trees from Central Germany (near Hanover) and Lower Austria were very significantly (at the 1-per cent level) superior in six-year height growth and in sixth-year leader elongation to trees from Sweden (Prov. of Ostergotland), and France (Prov. of Haute Loire). The German provenance was faster growing than other provenances tested at the 5-per cent level of significance, and it was faster growing than the Swedish provenance by 42 per cent. The annual sixth-year growth measurements were as reliable in determining the potentials of growth rate as the measurements of total heights. Provenances from Austria and France represented very significantly darker green foliages than those from Sweden and Germany. Traits studied are important in selecting better suited provenances for Christmas-tree and timber production in the Alleghany section of Western Maryland.
