| Abstract: | Endogenous elicitor(s) present in barley seeds induce the accumulation of antifungal substances effective against powdery mildew fungi. Antifungal substances induced by the treatment with barley seeds extract coincides with the one induced by the inoculation with compatible or incompatible races of powdery mildew fungi on thin-layer chromatography analysis. The resistance induced by the treatment with barley seeds extract correlates to the accumulation of the antifungal substances in barley leaves. Furthermore, the activity of phenylalanine ammonia-lyase was also induced by the treatment with barley seeds extract. |
