The effects of Fe resupply to Fe-deficient plants have been investigated in hydroponically-grown sugar beet. In the short-term (24 h) after Fe resupply, major changes were observed, although de novo chlorophyll (Chl) synthesis had not begun yet. Approximately 50% of the zeaxanthin was converted into violaxanthin, whereas the actual Photosystem II (PS II) efficiency increased by 69% and non-photochemical quenching (NPQ) and the amount of thermally dissipated energy decreased markedly (by 47% and… CONTINUE READING
