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, σ P S I I ′ is larger, and F v ′ / F m ( ST ) ′ and F v ′ / F m ( MT ) ′ are smaller than those of the dark-adapted condition, but the corresponding parameters possess good linear correlations. F m ( MT ) , F m ( MT ) ′ , F v / F m ( MT ) , and F v ′ / F m ( MT ) ′ , which are measured using the multiple-turnover protocol, are larger than those of the single-turnover protocol. The linear correlation coefficient between F m ( ST ) and
