Hüberli, D., Tommerup, I.C., Hardy, G.E.St.J. and Colquhoun, I.J. (1997) Temperature changes resistance of Eucalyptus marginata to Phytophthora cinnamomi. In: 11th Biennial Conference of the Australasian Plant Pathology Society, 29 September - 2 October, Perth, Western Australia.

Abstract

Eucalyptus marginata (Jarrah) varies in its resistance to infection by the introduced pathogen, Phytophthora cinnamomi. This trait has been exploited to yield jarrah clones ranging in resistance to P. cinnamomi. However, isolates of P. cinnamomi vary in their capacity to induce disease in resistant jarrah clones. We have shown that isolates differ in their growth rates in jarrah and marri (E. calophylla) tissue and in agar media. Disease outbreaks in jarrah, other native vegetation and horticultural crops due to P. cinnamomi are more likely to occur in warm moist conditions. These factors raise questions about the interactions between the pathogen, hosts and temperature, and the consequent disease development.
