Clones of Armillaria ostoyae and the pattern of infected juvenile lodgepole pine in Alberta, Canada

摘要

AbstractSmall patches of dead trees were common among 7‐ to 15‐year‐oldPinns contortavar.latifoliain Alberta, Canada. The sizes of clones ofArmillaria ostoyae, determined by pairing diploid isolates, was larger than these patches. Pairing diploid isolates on strips ofBetula papyriferaprovided a clear indication of clonal relation
