Abstract: Abstract： In order to study on the effects of different kinds of tree species parasitism by Armillariella mellea , fifteen woods were inoculated including solid and liquid treatment respectively. After the whole medium being full of rhizomorphs，germination time，growth rate，stout of rhizomorphs，weights were measured. The results shows：rhizomorphs on the Malus baccata and Quercus laevis germinating earlier and stronger，and have heavier dry weight, Castanea mollissima comes the second; The growth rate of rhizomorphs on Malus spectabilis is the fastest. There is no significant difference of rhizomorphs growth between the solid inoculations and liquid inoculations in the wood. Therefore, the branches of Quercus, Castanea , Diospyros kaki and Malus baccata are the suitable materials for the strains culture of Armillariella mellea.
