Abstract
intensity was set at 15, 40, 120 and 300 uEin m""^sec""^and temperature at !i, 10 and IS^'C.The saturation light intensity for optimal growth was approximately 120 yEin m""^sec""-^for Diatoma and Astevionella y and 40 yEin m""^sec"*^ for Fragilaria* Maximum growth rates for all three taxa were similar at 10'* and 18**C, but were significantly reduced at 5**C.Cellular chlorophyll conte^nt, however, was inversely related to light level, but was affected by temperature to a lesser degree.Growth rates from these experiments compared with results obtained from nutrient enrichment bioassays of natural phytoplankton communiL- ties indicate that the unialgal isolates of the three species have greater specific growth rates under culture conditions than were obtained from the same species in natural assemblages growing in enriched natural lake water*
