Haute prévalence de Fusarium spp. associés aux grains de céréales dans la région centrale du Maroc: risques pathogénique et toxinogène

39636

The prevalence and diversity of endophytic Fusarium species on freshly harvested cereals in the central region of Moroccowere assessed based on morphological, macroscopic and microscopic characteristics of the fungal flora isolated from 27 grainsamples of durum wheat (n=9), soft wheat (n=4), barley (n=8) and maize (n=6). The results revealed the presence of a variety offungal species. For all isolates (n=564), the genus Alternaria accounted for 53 % and was dominant in the 4 cereals followed bythe genus Fusarium (16 %), Aspergillus (14%), Rhizopus (8 %), Bipolaris (3 %), Abzidia (2 %) and others (4 %). In the genusFusarium, F. proliferatum (24 %) was the most common on the different cereals, followed by F. poae (17 %), F. solani (13 %), F.oxysporum (12 %) and F. Culmorum (10 %). The latter was associated only with durum wheat. The effect of sample geographicalorigin and plant species on the frequency of fungal species as well as their influence on grain health and quality are discussed.
