Abstract: Iron, added as (Fe-EDTA)-, was found stimulatory to V. spiralis at a concentration of 0.05 ppm. (Fe-EDTA)- had no effect upon growth of V. neotropicalis as measured by changes in dissolved oxygen and dry weight. Results are compared with those derived from similar studies with Hydrilla verticillata and Egeria densa. The implications of lake drawdown and aeration are discussed.
