Abstract
Using a measurement system based on fluorescence induced by variable pulse light, photosynthesis parameters of chlorella pyrenoidosa are obtained, employing single-turnover and multiple-turnover protocols under dark-adapted and light-adapted conditions. Under the light-adapted condition, σPSII is larger, and Fv/Fm(ST) and Fv/Fm(MT) are smaller than those of the dark-adapted condition, but the corresponding parameters possess good linear correlations. Fm(MT), Fm(MT), Fv/Fm(MT), and Fv/Fm(MT), which are measured using the multiple-turnover protocol, are larger than those of the single-turnover protocol. The linear correlation coefficient between Fm(ST) and
