| Abstract: | Results of fluorescence microscopic study and quantitative luminescent analysis of pathogen induced callose accumulation in winter wheat seedlings of two cultivars with different resistance to causal agent of eyespot disease are presented. Higher content of constitutive callose in intact seedlings of unsusceptible cultivar at the initial stages of vegetation was determined. It correlates with resistance of this cultivar to Pseudocercosporella herpotrichoides—causal agent of eyespot disease. The increased pathogen induced accumulation of callose in seedlings of susceptible cultivar was revealed, however, it did not influence it protection against pathogen. |
