“…Phenology study based on the same material in the Komi Republic revealed such later cessation of shoot growth of lodgepole pine vs. Scots pine and a latitudinal cline among lodgepole pine origins (Fedorkov 2010). A higher proportion of damaged trees with killed leader shoots for lodgepole pine seed sources of southern origins was recorded in fields trials studied in 2011 (Fedorkov 2012).…”

“…The tree vitality was about the same for lodgepole pine and Scots pine in Ukhta, Storojevsk, and Koygorodok field trials at the age of 4 years (Fedorkov and Turkin 2010), but at the age of 8 years tree vitality of Scots pine was better compared to lodgepole pine owing to frost damage in the end of winter and beginning of spring 2010 (Fedorkov 2012).…”

Highlights• Stem volume was bigger for lodgepole pine in comparison to local Scots pine except for the southernmost origin. • The proportion of stems with no defects was lower for all lodgepole pine seed sources than for local Scots pine. • Lodgepole pine stem growth traits were significantly related to latitude of seed origin. AbstractMortality, stem growth and quality of lodgepole pine (Pinus contorta var. latifolia) originating from the six Swedish seed orchards and local Scots pine (Pinus sylvestris L.) were estimated in four field trials established in the Komi Republic (north-west Russia). A randomized row-plot design with 6-12 replicates of each entry was used. The tree mortality was slightly higher for Scots pine than that for lodgepole pine, except for the lodgepole pine seed sources of the southern origins with lower survival. Scots pine stem quality was better than that of lodgepole pine, but the lodgepole pine stem growth was faster except the seed source of the southernmost origin. The lodgepole pine seed sources of northern origins had better stem growth (height, diameter at breast height and volume), while the effect of latitude on the quality traits was insignificant.
