Effect of variable retention cutting on the relationship between growth of coarse roots and stem of Picea mariana

摘要: Silviculture heading for structural heterogeneity creates many single trees standing at stand margins, inner edges or in remnant tree groups. As they played just a minor role the age class forest, growth behaviour of strongly released is rather unexplored. Here we show how retention cutting, presently spreading boreal Quebec province, affects stem and coarse root remained black spruce [Picea mariana (Mill.) Britton]. Increment cores from roots stems 125 that cutting triggers remaining trees. Compared with reference accelerate relation to growth. Mean variability root–stem allometry significantly rise after cutting. The found acceleration means mechanical stabilisation corroborates method. Evaluation silvicultural treatments can be incomplete misleading as long ...
