โœฆ Synopsis

One hundred different cultivars and lines of broad bean (Vicia faba L.) seed samples were inoculated with Aspergillus flavus Link (CMI 102135) to determine varietal differences which may support or resist aflatoxin production. Thin-layer chromatographic analysis of the chloroform extracts of the different seed samples revealed that 11 cultivars/lines were highly resistant to seed invasion and aflatoxin production while 9 cultivars/line showed partial resistance. The remaining 80 samples were susceptible to the establishment of A. flavus and aflatoxin accumulation. All the resistant cultivars/lines seed samples were inoculated also with three local isolates of fungi namely; Stachybotrys chartarum (Ehrenb. ex Link) Hughes, Aspergillus ochraceus Wilhelm, and Fusarium oxysporum Schlecht. The resistant seed samples were also resistant for colonization with these fungi and mycotoxin formation.

Seeds of faba bean cultivar GIZA 3 were screened for natural presence of mycotoxins. Eleven out of 100 samples were contaminated. Aflatoxins B, and B, were found in 7 samples while aflatoxins B,, B,, G , and G, and ochratoxin A were each detected twice in separate samples. Mycotoxins at concentratio

In broad been seeds (cultivars Comprimo RS and Threefoldwhite) harvested at four stages of maturity, which corresponded to dry matter content at the levels of I-25% , II-30% , III-35% and IV-40% , the content of amino acids was determined (g 16 g N-1). The determinations concerned raw broad bean and
