Effect of salts on the Hill reaction in sonicated spinach chloroplasts

摘要

KC1 stimulated the ferricyanide-Hill reaction at pH higher than 6.0 and at ferricyanide concentrations lower than 1 mMin sonicated spinach chloroplasts. However, KCl did not affect on the DCIP-Hill reaction at all. We concluded that Cl-is not an essential factor, but only a stimulator of the oxygen-evolving reaction of chloroplasts.
