Summary
Concentrations and contents of the micronutrients Fe, Mn, Zn, Cu, and B were measured in various tree compartments of a 16-year-old
stand of maritime pine (Pinus pinaster Soland in Ait.). The micronutrients were actively redistributed within the tree. The longer-lived aerial tissues, trunks
and branches, constituted the major micronutrient reservoirs, with the exception of manganese which accumulated in the needles.
