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
