Constitutional and Induced Accumulation of Callose and Phenol Compounds as Elements of Systemic Resistance in Winter Wheat Sprouts

Resumo

The amounts of accumulated callose and phenol compounds in sprouts of two winter wheat cultivars under inoculation with pathogenic fungus Pseudocercosporella herpotrichoides, the causing agent of wheat eyespot, were determined. Considerable differences were demonstrated in the constitutional and induced accumulation of phytoimmunity substances by the sprouts of the Myronivska 808 and Renan cultivars, which cause specific features of their resistance to pathogenic microorganisms.
