摘要

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'PSII 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.Fm(MT),F'm(MT),Fv/Fm(MT),and F'v/F'm(MT),which are measured using the multipleturnover protocol,are larger than those of the single-turnover protocol.The linear correlation coefficient between Fm(ST) and Fm(MT) is 0.984,and Fv/Fm(MT) =1.18Fv/Fm(ST).The linear correlation coefficient between F'm(ST) and F'm(MT) iS 0.995,and F''v/F''m(MT) =1.36F'v/F'm(ST).
