Abstract
Recently the development of techniques capable of measuring in vivo simultaneously the photochemical (qQ) and non-photochemical (qNP) components of chlorophyll fluorescence quenching, absorbance changes at 820 nm and photosynthetic gas exchange of leaves have allowed quantitative estimation of the quantum efficiencies of photosystems 2 (ϕPS2) and 1 (ϕPSl)and non-cyclic electron transport in leaves (1–6). These studies have provided evidence that non-photochemical processes associated with qNP could explain the observed reduction of quantum yield of open PS2 reaction centres as light intensity is increased (1–3,5,6).
