Summary The fine structure of the plastids in the leaf's basal meristem and in the leaf tissues 2 cm immediately above has been studied in maize leaves of different ages. In the young leaves the proplastids of the basal meristem differentiate, in the tissues within 2 cm above the meristem, into chloroplasts containing two or more prolamellar bodies, indipendently whether the tissues have been fixed 11 hours after a period of illumination or of darkness. In the oldest leaves, in the tissues immediately above the basal meristem, no prolamellar body is present in the plastids, and the proplastids differentiate directly into chloroplasts, without passing through an “etio-chloroplast” stage.
