Accumulation of calcium crystals in the decayed wood of aspen attacked by Fomes igniarius
IAWA Bull New Series
The concentrations of minerals were studied
in decayed, discoloured and clear wood of Aspen using both light and electron micro- scopes. Kevex X-ray energy spectrometer sys- telTI and atomic absorption spectrophotometer analyses revealed that the concentration of K, Na~ Ca, Mn, Mg were highest in the decayed wood and lowest in clear wood. Discoloured wood showed an intermediate concentration. Only crystalline calcium was present in the de- cayed wood and phloem. Association of wood rotting fungi seems to be closely related to the accumulation of calcium crystals.
