Verslag 2001 | Experimenteel onderzoek
In het verteringsproces van dood hout spelen paddestoelen een belangrijke rol. Het organisch materiaal wordt hierbij omgezet in anorganische voedingsstoffen, die op hun beurt kunnen opgenomen worden door de groene planten (mineralisatie). De omzetting of compostering van het dode hout verloopt grofweg in drie fasen:
Elke fase wordt gekenmerkt door specifieke paddestoelensoorten. In maart 1990 werd gestart met een onderzoek naar de successie van paddestoelen op 8 verschillende houtsoorten. Bij dit onderzoek kon vastgesteld worden dat bepaalde soorten op slechts 1 houtsoort voortkwamen, terwijl andere, minder selectieve soorten op meerdere houtstammetjes groeiden. In totaal konden er tot hiertoe tijdens het omzettingsproces 197 verschillende houtverterende paddestoelen worden aangetroffen. Het onderzoek wordt voortgezet. Hubert De Meulder |
