| Abstract: | Bicarbonate-dependent O2-evolving activity in dark-grown cotyledonsof Picea abies was measured with an oxygen electrode with differentpreillumination times. The activity showed a slight linear increasewith increasing preillumination time. On the other hand, O2-evolvingactivity (Hill activity) of chloroplasts prepared from preilluminateddark-grown cotyledons exhibited a characteristic change of asteep rise followed by a gradual increase with increasing preilluminationtime. The results obtained were discussed in connection withthe light activation of the latent, inactive O2-evolving centerin dark-grown cotyledons. (Received December 8, 1978; ) |
