Abstract

Acquired disease resistance can be induced in rose by acibenzolar-S-methyl(BTH), a novel synthetic chemical which has been shown to induce a broad-spectrum disease resistance in many plant species. BTH was applied by dipping whole in vitro rose shoots into the chemical at different concentrations for a few seconds before returning them to a shoot growth medium. Four dayslater, the shoots were challenge inoculated in vitro with D. rosae or A. tumefaciens under otherwise aseptic conditions. Pretreatment of rose shoots with 50 muM BTH led to resistance to Diplocarpon rosae and Agrobacterium tumefaciens by significantly reducing the disease severity of blackspots, percentage and mean size of crown galls formed, respectively.
