A cytophysiological study was carried out of the functional status of a halo as a response of the host plant to contact with a powdery mildew pathogen. Interactions of the powdery mildew causative agents with barley, wheat, wheat-wheat-grass hybrids, wheat-aegilops lines, and aegilops with different genotypic resistance lead to the expression of haloes(More)
Scanning electronic microscopy was used to investigate the regularities of growth direction of infectious structures and colonies of the agent of powdery mildew of wheat Erysiphe graminis f. sp. tritici. The growth of appressoria with normal morphology in wheat leaves occurs predominantly along the long axis of the cell. Most anomalous appressoria grow(More)
We studied the interaction between the pathogen and wheat-Aegilops lines with different resistance as well as their parental forms in the course of powdery mildew infection using scanning electron microscopy. Line 51/99i proved to be similar to the parental form, Rodina variety, by the infection progress. The both genotypes featured pronounced adhesion of(More)
Using methods of light and electron scanning microscopy, development and infection structures differentiation of the causal organism of wheat powdery mildew, Erysiphe graminis DC. f. sp. tritici March., was investigated under influence of exogenous zeatin. It has been shown for the first time that physiologically active materials, in particular, cytokinin(More)
