Abstract

This aquatic fern (A. pinnata) contains a blue-green alga (Anabaena) which fixes N and would be a potential source of nutrients for rice plants grown in tanks containing the fern. Attempts to cultivate it were hampered by rotting associated with Sclerotium rolfsii and Rhizoctonia sp., both of which were pathogenic to the fern in inoculation tests.
