    Abstract

    To assess the nutrient mobilization ability of myxomycete plasmodia in deadwood, a microcosm experiment was conducted. Alive or dead plasmodia of a common lignicolous myxomycete, Physarum rigidum, were inoculated on field-collected crushed wood powder of white-rot or brown-rot pine wood and incubated for 24 d. The activity of living plasmodia led to increased concentrations of Ca2+, K+, Mg2+, Na+, and Cl, but lower PO43– concentrations in the wood powder. For NO3 concentration, the effect of living plasmodia was negative in white-rotted wood but positive in brown-rotted wood. These results suggest that the plasmodium of P. rigidum has the ability to mobilize nutrients in deadwood.
