Fine root morphological adaptations in Scots pine, Norway spruce and silver birch along a latitudinal gradient in boreal forests
Variability in short root morphology of the three main tree species of Europe's boreal forest (Norway spruce ( Picea abies L. Karst.), Scots pine ( Pinus sylvestris L.) and silver birch ( Betula pendula Roth)) was investigated in four stands along a latitudinal gradient from northern Finland to...

description |
Variability in short root morphology of the three main tree species of Europe's boreal forest (Norway spruce ( Picea abies L. Karst.), Scots pine ( Pinus sylvestris L.) and silver birch ( Betula pendula Roth)) was investigated in four stands along a latitudinal gradient from northern Finland to southern Estonia. Silver birch and Scots pine were present in three stands and Norway spruce was present in all stands. For three fertile Norway spruce stands, fine root biomass and number of root tips per stand area or unit basal area were assessed from north to south. Principal component analysis indicated that short root morphology was significantly affected by tree species and site, which together explained 34.7% of the total variability. The range of variation in mean specific root area (SRA) was 5–74, 60–70 and 84–124 m2 kg−1 for Norway spruce, Scots pine and silver birch, respectively, and the corresponding ranges for specific root length were 37–47, 40–48 and 87–97 m g−1. The range of variation in root tissue density of Norway spruce, Scots pine and silver birch was 113–182, 127–158 and 81–156 kg m−3, respectively. Sensitivity of short root morphology to site conditions decreased in the order: Norway spruce > silver birch > Scots pine. Short root SRA increased with site fertility in all species. In Norway spruce, fine root biomass and number of root tips per m2 decreased from north to south. The differences in morphological parameters among sites were significant but smaller than the site differences in fine root biomass and number of root tips. |
