Abstract：
:It is shown that the protochlorophyllide ester pool of etiolated higher plants is a faithful copy of the protochlorophyllide pool. It is made up of both monovinyl- and divinylprotochlorophyllide esters. Although the two tetrapyrroles exhibited similar emission maxima, they were distinguishable by their Soret excitation maxima, which were found at 436-437 and 443-444 nm, respectively, in ether at 77K. The two pigments were partially separated on thin layers of polyethylene. They were accompanied by two unknown fluorescent compounds. It was also shown that during greening, the protochlorophyllide ester pool maintained a constant qualitative composition. This was in sharp contrast with the drastic qualitative changes undergone by the protochlorophyllide pool of etiolated tissues grown under identical conditions.
