Infection of exotic and Tasmanian native tree and shrub species by the vascular stain fungus Chalara australis

摘要

AbstractInoculation of stem pieces and living plants was used to assess the susceptibility of a range of exotic Fagaceous and Tasmanian native tree and shrub species to the vascular stain organismChalara australis. Development of inoculum on freshly cut stump surfaces of a number of species was also examined. The fungus has a limited host range but may produce inoculum on moribund surface tissues of non host species and is a potential hazard to otherNothofagusspecies growing both within Australia and elsewhere in the world.
