Abstract
The mechanism of benzimidazole-induced resistance against ozone damage was investigated using bean (cultivar Pinto 111) plants grown under controlled conditions. Water flux, water potential, electrolyte leakage, and osmotic potential measurements were made immediately and 48 hours after ozonation. Benzimidazole treatment alone increased water efflux of plants, water influx of ozonated plants, and appeared to increase the calculated hydraulic conductivity for these fluxes. Benzimidazole also decreased electrolyte leakage and had no effect on osmotic potential or water potential. Benzimidazole prevented the immediate ozone-induced electrolyte leakage, increased water potential, and decreased osmotic potential. It is proposed that benzimidazole changes some structural component of plant cell membranes.
