Cytochemical localization of sodium ion in the salt gland of <I>Lavatera arborea </I>(L.) was carried out. Electron enzyme-cytochemical procedure was also employed to locate sites of ATPase activities in the salt gland. There was a prominent localization of electron dense precipitates in the extracytoplasmic space near the wall separating the two secretory cells in the gland. Other sites of sodium ion precipitation were in the vacuoles, dilated parts of the plasmalemma invaginations and microvacuoles. The result of the ultrastructural study demonstrated that ATPase activities were prominent in all the above sites. The close parallel in the sites of sodium localization and the areas where intense enzyme reaction were produced supports the hypothesis that the salt gland is involved in short distance intensive ion transport. X-ray microanalytical study revealed that the major ions being secreted by the salt gland is that of sodium and chloride. |
