Susceptibility of plant species in coastal dune vegetation of south-western Australia to killing by Armillaria luteobubalina
Australian Journal of Botany 46 (2), 321-334
Abstract: Estimates of the susceptibility of plant species of coastal dune vegetation to killing by Armillaria luteobubalina Watling and Kilewere obtained from the occurrence of mycelial sheaths of the pathogen beneath the bark of the root collars of dead plants in 62 disease centres. Dicotyledons (Magnoliopsida) outnumbered monocotyledons (Liliopsida), being 81% of the 330 plant species found in disease centres in coastal vegetation. Fifty-one percent of the species were from five Magnoliopsida families with the largest number of species from the Myrtaceae and Proteaceae. Eleven percent of the species were from three Liliopsida families with the largest number of species from the Cyperaceae. Thirty-four percent of species occurred in three or more disease centres. Thirty-eight percent, or a total of 125 of all species, were killed by A. luteobubalina incoastal vegetation. Hosts on which the pathogen did not reach the root collar would not have been detected. The largest number of species killed were from the Proteaceae (26% of species killed) followed by Myrtaceae, Epacridaceae, Papilionaceae and Mimosaceae. Only 6% of species killedwere from the Liliopsida. The distribution of species frequency and those killed by infection is positively skewed, with 40% of species not killed in any centre and 8% killed in greater than 75% of the centres in which they occurred. The percentage of disease centres in which aspecies occurred and was killed by A. luteobubalina is significantly linearly correlated with mortality rating and relative importance. Cross-tabulation of species by disease centres in which plants were killed provided the opportunity to classify the relative susceptibility of plant species to killing by A. luteobubalina.
