Storage protein disappeared first from the peripheral and later from central parts of the lupine cotyledon. Kinetin (500 μM) stimulated this process; its effect was most prominent after longer times of incubation. In plastids large, crystalline prolamellar bodies were observed. They some-times split into smaller parts during the course of the experiment, especially in the kinetin-treated material. Kinetin in darkness did not stimulate formation of thylakoid membranes (neither grana nor primary lamellae)
