Determination of seedborne fungi and detection of aflatoxins in Sudanese fenugreek seeds
Phytoparasitica 30 (1), 61-66
Abstract: Following incubation of fenugreek (Trigonella foenum-graecum L.) seeds on potato dextrose
agar and moist filter papers at 28 ±2°C, 59 species and 11 varieties belonging to 21 genera of fungi were determined as seedborne in fenugreek crops. Among these isolates, 45 species and 9 varieties are new records for this crop; and two species are new to the mycoflora of Sudan: Aspergillus stellifer and Emericella variecolor. The genus Aspergillus (15 species and 8 varieties) is the most prevalent, followed by Drechslera (3 species), Rhizopus (3 species), Alternaria and Fusarium (6 species each), Emericella (4 species and 2 varieties), Cladosporium and Penicillium (4 species each), Chaetomium (3 species) and Curvularia (3 species and one variety). The remaining 11 genera displayed low level of infection. Of the common pathogens of fenugreek plants, Fusarium oxysporum (2.13%) was recovered from the seeds of this crop. Thin layer chromatographic analysis of chloroform extracts of 13 seed samples showed that two samples were naturally contaminated with aflatoxins B1, B2, G1 and G2 (7.5–35.2 µg /kg).
