Abstract
The reason for aflatoxin B1-induced non-germination of maize seed was investigated. It was observed that aflatoxin Bl (AFB1), produced by invading Aspergillus flavus. Link in seed, affects amylase activity, causing inhibition of starch (major food reserve) hydrolysis and consequent unavailability of sucrose (utilizable substrate) to the embryonic axis during the period of imbibation. The embryo of a toxin contaminated seed, nevertheless remains alive possessing fairly high dehydrogenase (respiratory) activity and is capable of growth in culture when supplemented with sucrose.
