Effects of Light on the Growth and Photosynthesis of Egeria najas Planchon Washington

Photosynthesis and growth of Egeria najas (Hydrocharitaceae) from a subtropical reservoir (Itaipu Reservoir , Brazil-Paraguay) were measured in response to low light intensities (0-124 μM m s PAR) in the laboratory. Photosynthesis approached saturation in the range of light intensities used and light compensation point was reached at ca. 6-22 μM m s PAR… CONTINUE READING
