Abstract : Total chlorophyll, carotene , xanthophull and total sugar were less in the seedlings of Cowpea raised from the seeds stored with Aspergillus flavus, A. niger and Fusarium moniliforme. As the RH of storage was raised from 60 to 80%, there appeared proportionate decrease in the noted bio-chemicals. A. flavus proved as the most deleterious followed in succession by A. niger and F.moniliforme. Glucose , fructose and sucrose that were detected as individual sugars in the seedlings were found distinctly less due to the seed borne fungi when stored with seeds at 80% RH.
