The Inhibition Effect of Alcoholic Extract of Capsicum Annuum (Chili Pepper) on The Growth of Barely Grains’ Associated Fungi Species

In this research, isolation and identification of some fungal species that were associated with barley grains (obtained from Misurata Agricultural Research Center) were carried out, to study the effect of their secretions on the germination and growth of barely seedlings. The ethanolic extract of Chili pepper was also tested for its biological control on the germination and growth of the chosen fungal species. 10 fungal species belonging to 4 different genera were isolated and identified from barley grains, among these, two species were selected (Aspergillus niger and Rhizopus stolonifer) for further investigation. Both of the two fungal filtrates showed an inhibitory effect on the germination and length of radicles of barley grains and seedlings, results also showed that ethanolic extract of Capsicum annuum (Chili pepper) had a varied inhibitory effect on spore germination of the selected fungal species, the reason for inhibition of fungi treated with C. annuum extract may be due to the presence of different chemicals have inhibitory effects on fungi.
