Fungi associated with caraway and cumin seeds and their aflatoxins production [ electronic resource].

Includes reference.

Blotter and deep-freezing methods recommended by International Seed Testing Association (1STA) were selected for detecting seed-borne fungi in caraway and cumin seeds. The total numbers of the detected fungi on caraway seeds were 26 and 22 species in blotter and deep freezing methods, respectively. However, on cumin seeds, were 25 species in blotter and 22 species in deep freezing method. Pericarp and mcricarp seed parts contained most of the associated seed borne fungi, while embryo contained lower one. Seeds of caraway and cumin stored for one year in polyethylene bags and Jute sacks under lab. conditions revealed 20 species of fungi in caraway seeds, while in cumin seeds only 19 species were detected by using Blotter method. The moisture content, germinability and aflatoxins production were determined monthly in the stored seeds. Using synthetic medium, only 7 isolates out of 55 Aspergillus flavus isolates obtained from stored caraway seeds produced aflatoxins, while 3 isolates only among 28 isolates from stored cumin seeds produced aflatoxin.
