The results obtained lead to the conclusion that under low irradiances all chlorophyll molecules are in a state to perform charge separation (photochemical) reaction, while under increased irradiances the essential part of the reaction centres are blocked and only one reaction centre from 500-600 remains in functionally active state, i.e. in the range of the value obtained by the founders of the widely accepted concept of photosynthetic units. | | Language | eng | | Pub Type(s) | Journal Article
