Abstract

Action sites of low positive temperature together with high light intensities in electron transport reactions of photosystem II (PSII) evaluated by ms range delayed fluorescence (ms-DLE) of chlorophyll a content in the maize and barley seedlings are presented. The main targets for these stress factors action were shown to be Yz and Mn4OxCa-cluster on the donor site of PSII in the case of simultaneous action of different temperatures and high light illumination and between QA and QB on the acceptor site of PSII in the case of low positive temperature influence only.
