Wound response of Eucalyptus clones after inoculation with Cryphonectria cubensis

Twenty-five different Eucalyptus grandis clones were artificially wounded a nd inoculated with a virulent: isolate of Cryphonectria cubensis. The capac ity of wounds to close through callus production was correlated with the re lative susceptibility of these clones to infection by C. cubensis. Clones w ith the greatest capacity to close wounds were those that were also most to lerant to C. cubensis infection. Those with a lower capacity to close wound s were most susceptible to Cryphonectria canker.
