The results of investigations on the development of chromoplast fine structures in various plants are reviewed. Emphasis is placed on the specific pigment-containing structures and their development during chromoplast formation. There is a large variety of these structures, although four fundamental types can be discerned.

As in non-irradiated etiolated material the grana formation is stimulated by an equal pre-illumination, it may be concluded that the observed phenomenon is not a consequence of protection or restoration processes but of a photomorphogenic effect which is independent even of gamma radiation.
