| Abstract |
Neither species grew actively at 17 mu mol/m-2/s, at which viable subpopulations retained the photoadaptational characteristics of the inoculum. Thus sudden transfer of algae to marginally low light arrests the photoadaptational response. Decreasing average fluorescence and volume per cell in slowly dying cultures of T. pseudonana was solely due to increasing prominence of a subpopulation of cells with abnormally low fluorescence and small volume. |
