ACCUMULATION OF SULPHUR IN AND ON SCOTS PINE NEEDLES IN THE SUBARCTIC
Water, Air, and Soil Pollution, 1997Total S concentrations of Scots pine (Pinus sylvestris L.) needles studied in the Finnish subarctic (66–70°N, 24–30°E) in 1990/1992 ranged from 573 to 1153 μg g−1 Levels were found to be ∼ 900 μg g−1 (i.e. 1.3–1.8 times the ‘normal’ level of 500–700 μg g−1 in areas where the long-term ambient SO2 concentration was ∼ 2–5 μg m−3, particulate SO

Spatial and temporal ecology of Scots pine ectomycorrhizas
New Phytologist, 2010Spatial analysis was used to explore the distribution of individual species in an ectomycorrhizal (ECM) fungal community to address: whether mycorrhizas of individual ECM fungal species were patchily distributed, and at what scale; and what the causes of this patchiness might be.

Seasonal development of phloem in scots pine stems
Russian Journal of Developmental Biology, 2006The formation of phloem was studied for two years in stems of 50 to 60 year old trees of Scots pine (Pinus sylvestris L.) growing in nature. The development of phloem of the current year begins 10 to 20 days before the xylem formation and is completed with the termination of shoot growth in the end of June.

Airborne chloronaphthalenes in Scots pine needles of Poland
Chemosphere, 2009The amounts, profiles and origin of CNs (from triCNs to octaCN) sequestered in Scots pine needles collected from 25 spatially distant sites in Poland have been studied based on congener-specific data obtained after a several clean-up and fractionation steps and final HRGC/HRMS separation and determination.

Mycorrhizal morphotypes of Scots pine
1998The significance of the ectomycorrhizal symbiosis for temperate forest stability is stressed by several authors (Read, 1991; Vogt et al., 1991; Dighton, 1995). In the presence of mycorrhizae litter decomposition is faster and release of nutrients from the litter is higher than in the absence of mycorrhizae (Zhu and Ehrenfeld, 1996).

Recovery of photosynthesis in winter‐stressed Scots pine
Plant, Cell & Environment, 1990Abstract. . Winter‐induced inhibition of photosynthesis in Scots pine (Pinns sylvestris L.) is caused by the combined effects of light and freezing temperatures; light causes photoinhibition of photosystem II (Strand & Oquist, 1985b, Physiologic Plantarum, 65, 117–123), whereas frost causes inhibition of enzymatic steps of photosynthesis (Strand ...

Growth analysis of Scots pine and lodgepole pine seedlings
Forest Ecology and Management, 1996Abstract Possible reasons for the superior growth rate of lodgepole pine (LP) (Pinus contorta Dougl. var. latifolia Engelm.) compared to Scots pine (SP) (Pinus sylvestris L.) were investigated in a trial where the species were grown in large pots with sand, till or topsoil, during 4 years following sowing.
