Change in the proteinase-inhibitory system of wheat and barley associated with resistance to fusariose

摘要

The activity of neutral (pH 6.0), acid (pH 3.5) proteinases and content of inhibitor trypsin were studied on the six-day winter wheat seedlings (Triticum aestivum L.) and spring barley seedlings (Hordeum vulgare L.) under the action of salicylic acid. It was established that different genera of cereal crops were characterized by different character of change of the proteinase-inhibitory complex. The conducted reseach is an evidence of existance of the common mechanisms of genetic determination of cereals root system resistance to Fusarium graminearum species preservation.
