Abstract |
Ponderosa and Jeffrey pine sapwood samples and freshly cut stumps from trees with different amounts of oxidant injury were inoculated with Fomes annosus. With stumps, percentage of surface cross-section area infected and extent of vertical colonization were determined 1 mo and 6-10 mos after inoculation, respectively. Increase in surface area infection with increased oxidant injury, expressed as upper-crown needle retention was statistically significant for ponderosa pine (P=0.01), but was not for Jeffrey pine. Also, the rate of vertical colonization was greater in stumps from severely oxidant-injured trees than in those from slightly injured trees. The relationship between injury and colonization was significant for Jeffrey pine (P=0.05) and for ponderosa pine at one site (P=0.03), but nonsignificant (P=0.18) for ponderosa pine at a second site. Increased susceptibility of stumps to F. annosus appeared to be associated with decreased oleoresin exudation and decreased colonization by other fungi (especially Trichoderma spp. and blue stain fungi).
