Considerații cu privire la interacțiunile grâu – patogeni fungi în contextul schimbărilor climatice

Abstract

It was established that the environmental conditions strongly influence the fungal spectrum that causes the root rot of the stem base to common wheat in the conditions of the Republic of Moldova. In more severe conditions (high temperature, drought) the incidence of Fusarium equiseti increases. The interaction of common wheat with one of the causative agents of stem rot – F. oxysporum is determined by the combination, the orientation of the cross to obtain F1 hybrids, the temperature factor, which has a direct impact on seedling growth and transgressive potential of F2 segregating populations, a phenomenon with major importance for the improvement programs.
