抄録

In this study, chlorophyll fluorescence imaging of the maximal yield in the dark was applied to estimation of cell concentration of <I>Amphidinium</I> sp. As the result, a linear relationship was observed between chlorophyll fluorescence intensity and cell concentration. It was revealed that the method enabled rapid measurement of cell concentration without effect of chlorophyll fluorescence induction. To investigate the effect of light qualities during the culture on photosynthetic activities of <I>Amphidinium</I> sp., changes in Φ<SUB><I>PSII</I></SUB> of the algae cultivated under red, blue and red+blue lights were compared. As the result, the Φ<SUB><I>PSII</I></SUB> of algae cultivated under red+blue light was higher than that under blue light. It was implied that the light quality affected the efficiency of the photosynthetic electron transport. Meanwhile, the Φ<SUB><I>PSII</I></SUB> of algae cultivated under red light was similar to that under red+blue light in spite of its low growth rate. It was implied that the heat dissipation of <I>Amphidinium</I> sp. cultivated under red light did not increase because their low chlorophyll concentration led to low light absorbance.
