Abstract

The present investigations were carried out on seeds of the spring wheat var. 'Kolibri'. Storage was at either 12 or 15% moisture seed content, and temperature degrees of labile, 0°C, 25-30°C for a periods extended to 18 months. Seeds remained -healthy at 12% M. C., and 15% and 0°C. Mycological analysis of frosh and stored seeds revealed great difference among their fungal flora. Sporadic amounts of certain fungal pathogens, from the <i>Fusarium</i> genus, were isolated from seeds. In relation of seed-borne fungi to the health stale of plants developing, results of pot experiments showed the possibility of spread certain pathogens of <i>Fusarium</i> from seed to stem of the developing plant. The fungal communities of seeds or plants does not limit, in general, the development of these pathogens <i>Fusartum culmorum, F. poae, F. equiseti. Fusarium culmorum</i> was found, under the present work, to be a most severe infectous agent of foot rot disease of wheat crop var. 'Kolibri'.
