Abstract
The ultrastructure of hypocotyl, epicotyl, and petiole of bean (Phaseolus vulgaris, L.) was investigated in plants grown in a basic solution in the absence or presence of high levels of chloride salts. The hypocotyl tissue of both control and salt-treated plants showed frequent vesiculation similar to that previously observed in the root and hypocotyl of the halophyte, Salicornia europea, L. These vesicles were not previously observed in the root and leaf of bean plants that were grown under identical conditions in the absence of high levels of chloride salt. Experiments concerning the localization of chloride as electron-dense silver-complex showed that the vesicles contain a chloride concentration as high as the cytoplasmic phase or the free space. These results are discussed in relation to the ionic retention property of the bean hypecotyl and the role of vesiculation in salt resistance of plants.
