Microfungi Associated with Floral Parts of Vigna Sinensis (L.) Savi Ex Hassk

The present work is of microfungi associated with floral parts of Vigna sinensis, it was observed that, in all 20 species belonging to Zygomycotina (4) and Deuteromycotina (16) were encountered during four samplings. Numerical distribution of average number of fungi broadly increased from the first to the last stage of sampling. On sepals only one fungal species belonged to Zygomycotina and 9 from Deuteromycotina were recorded. On petals, the fungi isolated 4 belonged to Zygomycotina and 14 belonged to Deuteromycotina.9 and 8 species were isolated from stamens and carpels respectively and all belonging to Deuteromycotina. Fungal species which were consistently associated with flowers consisted Alternaria alternata, Aspergillus flavous, Cladosporium cladosporioides, Curvularia lunata and Fusarium moniliforme. The whole mount preparations of stamens along with pollen grains revealed that thick, dark brown, branched and septate hyphae of Alternaria alternata were surrounding the exine of some of the pollen grains with dense aggregation of hyphae was observed which finally invading them.
