Abstract
The role of root endophytic aquatic hyphomycetous fungi in plant health was studied by employing pot experiments. Three aquatic hyphomycetous fungi Heliscus lugdunensis, Tetrachaetum elegans and Tetracladium nainitalense isolated as root endophytes of riparian plants were artificially inoculated into two test plants viz., Solanum melongena and Hibiscus esculentus. T. elegans and H. lugdunensis showed significant effects (fresh weight, dry weight and length of shoots and roots) on both test plants, whereas T. nainitalense had no effect.
