Inoculations of callus generated from micropropagated shoots of Cupressus semper iii, ens, Cupressus macrocarpa, Cupressus torulosa and Chamaecyparis lawsoniana showed that callus of species resistant or relatively resistant to Seiridium cardinale supported significantly less surface growth of the pathogen than callus of susceptible species. In dual cultures of Cupressus sempervirens or Cupressus torulosa callus with S. cardinale, inhibition of fungal growth towards the callus was correlated with known field resistance of these host species. Lignification, accumulation of polyphenolics and possible suberization of cell wails were detected in inoculated callus. This response was also correlated with known field resistance of the tested host species.
