【 摘 要 】

Flash-induced absorption changes were measured in the 390–450 nm region, using whole cells of a double mutant strain of Chlorella sorokiniana, lacking PS I centers and part of the pigment antenna. Spectral changes associated with PS II acceptors (Q_a and Q_b) and donors (p₆₈₀, Z and L) are described. In this region, the spectrum obtained for Q_b ⁻/Q_b differs markedly from that of Q_a ⁻/Q_a. Different spectra were also obtained for the secondary donor (Z⁺/Z) when measured after one or three flashes.
