In Morocco, saffron is
grown in the areas of Taliouine (provine of Taroudante) and Taznakht (province
of Ouarzazate). Studies on fungi related to this crop are still very rare.
Mycological studies on mycoflora associated with Saffron (Crocus sativus) from
the main producing area, located in the Taliouine region was carried out
between September (corms for cultivation) and December (soil and roots of
saffron plants), 2018. The samples (corms and roots with symptoms) were cut up
in fragments and disinfected with alcohol. Then, these fragments were cultured
on Potato Sucrose Agar and incubated in the growth chamber for 7 days at 28°C.
The pure cultures obtained were identified morphologically and microscopically.
The fungal complex identified in the soils, corms and roots of saffron plants
was almost identical, including Fusarium solani, F. oxysporum, F. culmorum, F.
roseum, Fusarium sp., Aspergillus fumigatus, A. niger, Trichoderma sp.,
Rhizopus oryzae and Penicillium sp. Species of the genus Fusarium, considered
as true pathogens of different crops, are the most represented, with isolation
percentages ranging from 6 to 20%. Trichoderma sp., a biocontrol agent against
various pathogens, has also been isolated from the soils, corms and roots of
saffron plants, with a percentage of isolation ranging from 8 to 13%. This is
the first time that the species of the genus Fusarium (F. solani, F. culmorum
and F. roseum) and Trichoderma have been isolated in Morocco from Crocus
sativus.
