This study has been carried out to investigate the ultrastructural changes in the associated with the disintegration of the storage materials in endosperm cell of ginseng (Panax ginseng C.A. Meyer) seed during after-ripening with light and electron microscope. The protein body of endosperm cells near the umbiliform layer showed various degenerative patterns, and so electron density of proteinaceous matrix was gradualJy decreased during afterripening. These results indicate that the decomposition of endosperm was already initiated during after-ripening. As the degeneration of endosperm was more progressed after the dehiscence of seed, non-decomposed part of protein body appeared amorphously with high electron density. Decomposed protein bodies were vacuolized with the loss of their matrix and gradually expanded by fusion. Also, spherosomes were gradually dissolved with the lowered electron density during the degeneration of endosperm. The vesicles of dictyosomes near the cell wall are observed in endosperm contacting with umbiliform layer and are fused with plasma membrane. Umbiliform layer which was the complex of the decomposed remnants of lysis and materials has strong stainability for toluidine blue and basic fuchsin.
