Root chemistry of mature dogulas-fir differs by habitat type in the interior northwestern united states

摘要

Carbon compound concentrations in plant tissues depend on the environment in which plants grow. However, little is known about how these concentrations vary across a range of forest environmental conditions. Our study examined root tissue(phloem, cambium, phellum, and phello- derm)collected from naturally regenerated mature Douglas-fir(Pseudotsuga menziesii var. glauca [Bessn.]Franco)trees in eight stands on three habitat type series encompassing a range of temperature and moisture conditions.
