Identification of Microflora Associated with Groundnut (<i>Arachis hypogaea</i> L.) Seeds and Its Impact on Physical Impairment on Seeds Germination Percentages

This study was to investigate the incidence of seed-borne fungi on the groundnut seeds isolate and identify the seed-borne fungi associated with some of groundnut seeds and obtain information on the pathological effect of these fungi on the peanut seed germination. The results of these investigations revealed the existence of four notable seed-borne fungal pathogens, specifically A. niger, A. flavus, A. tamre, and one Aspergillus pp., in the designated research area. A. niger was identified as the predominant fungus affecting groundnut seeds among these pathogens. This finding suggests that the presence of A. niger might inhibit the growth of other fungi through competitive interactions in the environment. Previous research by Ohave. The findings are consistent with the results of my study, which demonstrate that these fungi play a role in causing pathological effects on groundnut seeds, resulting in issues such as seed shriveling, discoloration, and decreased germination rates due to seed-borne fungal infections. The conducted study emphasizes the importance of treating seeds purchased from markets with fungicides prior to planting to prevent seedborne diseases like seed rot, decay, and other related pathologies. Furthermore, it is very important to take steps to reduce the spread of seed-borne pathogens and the production of mycotoxins in groundnut seeds by improving storage conditions, which include maintaining low temperatures, humidity levels, and moisture content. Additionally, preventive measures should be implemented to avoid damage during post-harvest processes at storage and during the sale at the market.
