| Research Abstract |
Pulse Amplitude Modulation(PAM)method is used to evaluate photosynthesis activities for algae. In this study, estimation of primary productivity of stream bed periphyton was applied. Handy Fluor Cam was used to obtain horizontally two dimensional distributions. As a result, there is correlation between the minimum fluorescence yield Fo and the biomass for green algae and filamentous algae. There is relatively high correlation between the maximum fluorescence yield Fm and diatom. For direct measurement in field, the dark condition and enough amount of algal biomass are necessary.
