Evaluation of photosynthetic capacity in phytoplankton by flow cytometric analysis of DCMU-enhanced chlorophyll fluorescence

Abstract

Using a mercury-cadmium arc lamp-based flow cytometer, the authors found significant correlations between fluorescence enhancement and photosynthetic capacity. The correlation was dependent on species and growth irradiance. The method was applied to natural assemblages in Bedford Basin (Canada): temporal variations of fluorescence enhancement were clearly evident in dominant diatoms and cryptophytes. -from Authors
