We studies the seasonal dynamics of phenolics in leaves, litter and soil
of the dominant host tree oak (Quercus robur L.) growing with
ectomycorrhizal fungi truffles (T. macrosporum) in oak forest (Fraxino
angustifoliae-Quercetum roboris Joy. et Tomic 1979) near River Danube,
near Belgrade. In litter, the highest content of free phenolics was in
April (primordial growth period of truffles) and bound phenolics in
August (truffles ripening- start of harvest). Due to intensive
decomposition of forest litter during the vegetative growth period, free
phenolic acids increased and the bound phenolic acids decreased. There
was reduction in ratio of bound cinnamic to benzoic acids, it indicated
the microbial degradation of lignin and the transformation of cinnamic
derivatives into benzoic acid derivatives. In the top soil layer, where
the majority of truffle fruit bodies were found (28.31 kg/ha/year). the
free phenolics (direct influence on truffle growth and development)
contents were up to 58.36 mu g/g. As the mycelia and fruit bodies of
truffle grow in phenolic-rich forest soil, hence, we assumed that the
truffle is well-adapted to high phenolics content.
