Abstract

Effects of light intensity and irradiation time on respiration rate in the dark period after irradiating are discussed. The specific respiration rate of S. platensis in the dark is a constant value Q₁, up to 15-30 minutes, and then rapidly decreases to Q₂ after 30 minutes. The specific respiration rate Q₁ increases with light intensity. No significant effect of Q₁ on irradiation time and Q₂ on light intensity is observed. The respiration rate for a long dark time, Q₀ (= 1.2 mg-O₂·kg-Spirulinct^-1·s^-1), is almost the same as Q₂. The effect of the logarithmic mean light intensity I_1m [k1x] on Q₁ is described by the following equation.<BR>Q₁-Q₀=13I_1m/15+I_1m
