title: [Polarization of prompt and delayed fluorescence of photosystem II].
abstract: Prompt and delayed fluorescence polarization of the oriented samples of synchronous. Chlorella vulgaris culture is investigated. Two main components with different polarization are revealed in the prompt and delayed fluorescence, however its ratio depends on the emission nature. The delayed fluorescence polarization ratio indicates that the reaction center pigment of PS-II dipole transition moment is in the photosynthetic membrane plane. The heterogeneity of variable and delayed PS-II fluorescence emission can be explained by the existence of two components: one of them is related to pigment-protein complex of PS-II (PPC-II) structurally and migrationally connected with LH-complex (alpha-component), but the other one--to PPC-II setting apart from the main LH-complex bulk (beta-component).
