“…Growth rhythm results (Paper III) were in line with Russian provenance trial in Komi Republic (61°39′N, 50°41′E, 160 m), where the northern provenances had earliest growth onset (the Dahurian larch provenances were not included into Komi trial) (Fedorkov 2012). Highest leader shoot growth was shown by 2A Plesetsk provenance instead of southern provenances.…”

“…Finnish and Swedish results differ from those of Norwegian field test in maritime Bergen (60°N, 5°E), where Olga Bay larches had highest survival after three growing seasons (Øyen et al 2007). In Komi republic in Russia (61°39′N, 50°41′E, 160 m), the survival on the second growing season in the field was high and varied between 92% and 97%, but in addition to the younger age, fewer provenances were included in the trial (Fedorkov 2012).…”

The aim of this study was to analyse the growth rhythm, height growth and survival of seedlings of 20 Russian larch (Larix Mill.) provenances and five comparison entries in sowing year in greenhouse conditions and in field conditions in southern (Punkaharju 61°49′N, 29°19′E) and northern (Kivalo 66°19′N, 26°38′E) Finland after third and fourth growing seasons. Geographic and climatic conditions of the origins were used to explain the differences between the provenances. In the sowing year in greenhouse, latitude explained 74% of the length of the growing period. In the field in Punkaharju, the northern Siberian larches (Larix sibirica Ledeb.) had the earliest bud burst and the Dahurian larch (Larix gmelinii Rupr.) provenances slightly earlier onset of height growth. The temperature sum and latitude of the provenances explained the differences in shoot elongation. After four growing seasons in the field northern provenances had the best survival and height growth in Kivalo. Survival did not differ significantly between provenances in Punkaharju field experiment. The southern Dahurian larches had a superior height growth in Punkaharju and they had least mammal damages. In Punkaharju, the growth cessation was affected by photoperiod and possibly by declining temperatures in autumn. Provenances from cold northern climates developed their terminal buds first. They also formed autumn colouring and shed their needles earlier than more southern provenances. Dahurian larches showed potential in height growth and ability to utilize the length of the growing season effectively in Punkaharju. They also seemed to have, on average, smaller amount of mammal damages. Despite this, the currently used Siberian larch of Raivola origin is still the safest choice for larch forestry in whole Finland in terms of adaptation to climate. Further studies are needed still on the potential offered by different species and provenances (and their hybrids) to generalize the findings of this work.

“…It is well known that late growth cessation in autumn is strongly related to the risk of frost damage (Aitken and Hannerz 2001). 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).…”

“…Statistical insignificance of this superiority (Table 4) may be partly explained by row-plot design of field experiments employed in our study which is less efficient in comparison with single-tree plot design. Reasons for the superior growth of lodgepole pine under boreal condition may be an earlier start of growth in spring and a lower required heat sum to start shoot elongation in comparison to Scots pine (Fedorkov 2010).…”

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.

“…It has been found that with longer rotations, existing Swedish lodgepole pine stands are also useful for timber production, since their stem volume is approximately 30% greater than that of the dominant pine species in Fennoscandia, the Scots pine (Elfving et al 2001). Reasons for the superior growth of lodgepole pine under boreal conditions may be an earlier start of growth in spring and a lower required heat sum to start shoot elongation in comparison to Scots pine (Fedorkov 2010).…”

Backlund, I. & Bergsten, U. 2012. Biomass production of dense direct-seeded lodgepole pine (Pinus contorta) at short rotation periods. Silva Fennica 46(4): 609-623.Lodgepole pine (Pinus contorta) is a fast-growing species that is suitable for producing woody biomass in Nordic countries. Direct seeding of this species is cheaper than planting and creates dense, stable stands. The objective of this study was to quantify the stem volume and biomass production of direct seeded lodgepole pine stands grown under different site conditions with different stem densities, at an age that would permit extensive harvesting of biomass. A circle-plot inventory was performed in 16 of the oldest direct seeded lodgepole pine stands in mid-northern Sweden. Stemwood production of almost 200 m 3 /ha was achieved on average on the best sites, rising to about 300 m 3 /ha for the best circle-plots within 30 years of direct seeding despite the fact that pre-commercial thinning was made once or twice. This corresponds to 100 and 140 tons of dry weight biomass/ha, respectively. Higher stand stem densities (≥ 3000 st/ha) yielded more biomass with only slight reductions in diameter at breast height. The development of stem volume with respect to dominant height in direct seeded stands was becoming comparable to that in planted stands with similar spacing. It therefore seems that there is an unutilized potential for cost-effectively growing lodgepole pine in dense stands for biomass production after direct seeding. It may be possible to devise regimes for short(er) rotation forestry that would yield substantial amount of inexpensive biomass for biorefineries within a few decades.
