[Delayed chloroplast luminescence. Activation and suppression].
Effect of diethyl ether, detergent triton X-100, glycerine, sucrose and preliminary heating on delayed luminescence (DL) of chloroplasts has been studied. Ether and triton X-100 in concentrations activating electron transport inhibit DL acting similarly to photophosphorylation uncouplers. Preliminary heating to 42-42C, glycerine and sucrose activate both the electron transport and DL of chloroplasts. Activation of electron transport under these agents is suggested to result not from photophosphorylation uncoupling, but from the changes in the conformation of chloroplast memebranes.
