Responses in the bark of Cupressus sempervirens clones artificially inoculated with Seiridium cardinale under field conditions
European Journal of Forest Pathology 29 (2), 135-142
Abstract: By 70 days after inoculation, resistant and tolerant clones of field-grown Cupressus sempervirens restricted penetration of the bark by Seiridium cardinale, forming ligno–suberized boundary zones which included four to six layers of cells with suberized cell walls. This response contrasted with that in susceptible clones, where only two to four layers of suberized cells were formed in discontinuous bands around inoculation sites. Detection of multiple layers of thin suberized boundary zones in susceptible clones indicated repeated penetration of the wound/infection–induced barrier by S. cardinale during a single growing season. The methods described will be valuable in the development of rapid, early and accurate screening programmes for durable resistance to Seiridium canker in Cupressus species.
