Abstract

Phellinus pini var. cancriformans and P. pini var. pini on white fir Abies concolor and balsam fir A. balsamea, respectively, initiated a nonspecific host response in phloem and xylem. Although many barrier zones are formed, often several within one annual ring, the fungus was not effectively compartmentalized. Successful penetration or evasion of barrier zones resulted in canker enlargement by both fungi. Phellinus pini var. cancriformans caused a typical white rot decay of heartwood in white fir whereas P. pini var. pini in balsam fir caused a selective delignification of wood. -from Author
