| Abstract | ||
| The effects 0 f gamma-irradiation 0 n chemical composition 0 f some different crop seeds, fungal infection a nd aflatoxin 81 production by Aspergillus flavus were investigated. Asp < /em>ergillus flavus infected seeds behaved differently according to their principal constituents. Aspergillus flavus caused an increase in protein and a decrease in lipids and carbohydrate contents of wheat, soyabean and fababean seeds. Growth of Aspergillus flavus and production of aflatoxin 81 was inhibited at a dose level of 5 kGy. Aspergillus flavus utilized carbohydrates of the seeds for its growth and aflatoxin production. Crops were arranged, in a descending order according to aflatoxin produced in seeds as, wheat > soyabean > fababean. There were no changes in chemical constituents of irradiated seeds, such as protein, lipids, and carbohydrates. | ||
