Effect of extracts of various plant parts on seed mycoflora and seed germination of Solanum xanthocarpum.
During the present studies total fourteen fungi were found to be associated with the seeds of Solanum xanthocarpum. The seeds of Solanum xanthocarpum show maximum seed mycoflora with maximum percent incidence. Aspergillus niger, Rhizopus nigricans, Aspergillus flavus, Fusarium moniliforme, Curvularia lunata and Rhizopus stolonifer were the common and dominant seed borne fungi of Solanum xanthocarpum. The common and dominant seed borne fungi were found to be inhibitory for seed germination and caused great loss in seedling vigor, seed and seedling rots of the Solanum xanthocarpum. The root stems, leaf and bark extracts of some common and easily available plants were screened for the Bio-control of the seed mycoflora of the Solanum xanthocarpum. Root, stem and leaf extracts of all the test plants were found to be inhibitory in more or less degree for the incidence of seed mycoflora while with a few exceptions, they were found to be stimulatory for seed germination.
