Growth studies ofAzolla pinnataRBr. in a permanent pond

Abstract
The growth pattern of A. pinnata, in association with Spirodela polyrhiza, was studied in a permanent pond. These 2 plants would provide a regular source of biomass. The suitability of integration of A. pinnata into other aquatic plants.sbd.based wastewater treatment systems was proposed. The favorable qualities offered by A. pinnata as a component in wastewater treatment systems was emphasized.
