FIG. 2.

Experiment three: mean extent of colonization of stems (± standard error), expressed in cm, for tree species and Heterobasidion genotype. Pa, A, (PaxA)p, and (PaxA)a refer to the following genotypes, respectively: H. parviporum, H. abietinum, H. parviporum × H. abietinum carrying H. parviporum mitochondrion, and H. parviporum × H. abietinum carrying H. abietinum mitochondrion. PaxA indicates the two hybrid genotypes combined. Shared letters indicate nonsignificant differences between Heterobasidion genotypes within each of the two inoculation trials, as determined by separate ANOVAs.
