| Abstract: | Chloroplasts isolated from barley (Hordeum galgare L.) seedling grown in liquid solution and from Zot,era marina and Codium fragile collected in summer and autumn of 1992 at Huiquan Bight of Qingdao Were used in this study on the rela-tionship between Mg2+-induced Chla fluorescence change and Mg2+-induced thylakoid surface charge alteration in chloroplasts. Result shows that Mg2+-induced Chla fluorescence intensity increase from PS-II closely correlated with Mg2+-induced electric charge density decrease on the outer surface of the thylakoid in the chloroplasts from barley and Zostera marina. However, under the same conditions the correlation was not noted in the chloroplast from Codium jragile. These experimental results not only demonstrated that the regulating effect of the cation on excitation energy distribution between two photosystems was controlled by the electrostatic property of the thylakoid surface in the chloroplasts of barley and Zostera marina and not controlled by the electrostatic property of the thylakoid surface in the. Chloroplast of Codium lragile, but also illustrated that these two kinds of regulating mechanisms did not depend on the growing environment of plants while they might be associated with the evolutional level of plants. |
