Estimates of thylakoid electron transport rates (Je) from chlorophyll fluorometry are often used in combination with leaf gas exchange measurements to provide detailed information about photosynthetic activity of leaves in situ. Estimating Je requires accurate determination of the quantum efficiency of Photosystem II (ΦP), which in turn requires momentary light saturation of the Photosystem II light harvesting complex to induce the maximum fluorescence signal (FM′). In practice, full saturation… 
Closing in on maximum yield of chlorophyll fluorescence using a single multiphase flash of sub-saturating intensity.
Through experiments and simulations, it is demonstrated that the rate of variation in irradiance during an MPF is critical for achieving quasi-steady-state changes in the proportions of PSII acceptor side redox intermediates and the corresponding fluorescence yields, which are prerequisites for accurately estimating Fm' at infinite irradiance.
Leaf Chlorophyll Fluorescence: Background and Fundamentals for Plant Biologists
This review on chlorophyll a fluorescence starts with an overview of the primary photochemistry occurring at PSII and a characterization of the so-called “open” and “closed” states of its reaction

Deriving C4 photosynthetic parameters from combined gas exchange and chlorophyll fluorescence using an Excel tool: theory and practice.
An accessible summary of the theory behind the analysis and derivation of C4 photosynthetic parameters is presented, and a freely available Excel Fitting Tool (EFT) is provided, making rigorous C4 data analysis accessible to a broader audience.
Physiological Limitations to Photosynthetic Carbon Assimilation in Cotton under Water Stress
Combined leaf gas exchange/chlorophyll fluorescence measurements differentiated the treatments more effectively than gas exchange measurements alone, and physiological restrictions to photosynthesis in leaves of water stressed cotton plants in a series of greenhouse experiments were investigated.
Electron Transport Through Photosystem II Is Not Limited By A Wide Range of Water Deficit Conditions In Field‐Grown Gossypium hirsutum
It is concluded that photosynthetic electron flow through photosystem II is insensitive to water deficit in field-grown G. hirsutum.
On measuring the response of mesophyll conductance to carbon dioxide with the variable J method
Analysis of calibration relationships for Populus trichocarpa found measurement errors, calibration non-linearities leading to bias, and the sensitivity of variable J gm hinders its use under conditions of varying CO2 or light.
Rapidly reversible chlorophyll fluorescence quenching induced by pulses of supersaturating light in vivo
A special type of non-photochemical quenching, HIQ, is reported, which is rapidly induced by a pulse of high-intensity light, when PS II reaction centers are closed, and rapidly relaxes again after the pulse, in line with the working hypothesis of HIQ being caused by the annihilation of singlet excited chlorophyll a by triplet excited carotenoid.
Three Methods of Estimating Mesophyll Conductance Agree Regarding its CO2 Sensitivity in the Rubisco-Limited Ci Range
Whether the mesophyll conductance to CO2 movement within leaves of C3 plants changes with CO2 concentration remains a matter of debate, particularly at low CO2 concentrations, and change in gm with Ci in the Rubisco-limited region of A vs. Ci curves depended on the species, but not on the method of estimating gm.


Maize Leaf Absorptance of Photosynthetically Active Radiation and Its Estimation Using a Chlorophyll Meter
Regression analysis revealed a strong relationship (r 2 = 0.98) between leaf absorptance and SPAD value, suggesting that the SPAD meter could be used to provide a rapid estimate of leaf absorPTance in the field.
Light dependence of quantum yields of Photosystem II and CO2 fixation in C3 and C4 plants
The light dependence of quantum yields of Photosystem II (ΦII) and of CO2 fixation were determined in C3 and C4 plants under atmospheric conditions where photorespiration was minimal and suggests a strong linkage between the true rate of CO 2 fixation and PS II activity under varying light intensity.
In situ estimation of net CO2 assimilation, photosynthetic electron flow and photorespiration in Turkey oak (Q. cerris L.) leaves: diurnal cycles under different levels of water supply
Combined measurements of gas exchange and chlorophyll a fluorescence under low O2 concentrations allowed the demonstration of a linear relationship between the photochemical efficiency of PSII (fluorescence measurements) and the apparent quantum yield of gross photosynthesis (gas exchange).
Gas exchange measurements, what can they tell us about the underlying limitations to photosynthesis? Procedures and sources of error.
Determining the rate of photorespiratory release of oxygen (Rl) has previously only been possible by isotopic methods, now, by combining gas exchange and fluorescence measurements, Rl may be determined simply and routinely in the field.

Whole-leaf photosynthesis is limited by gas phase, mesophyll diffusion, and carboxylation resistances in nearly the same proportion in both herbaceous species and trees.
Measurements of mesophyll conductance, photosynthetic electron transport and alternative electron sinks of field grown wheat leaves
Photosynthetic electron transport in flag leaves of wheat was estimated by the fluorescence method and gasexchange method to determine the possible magnitude of alternative electron sinks and the comparison of fluorescence and gas-exchange based methods for measuring the rate of electron transport could be used to estimate the mesophyll conductance to CO2 diffusion.
Relationship between thylakoid electron transport and photosynthetic CO2 uptake in leaves of three maize (Zea mays L.) hybrids
Under steady-state conditions, a linear relationship between ETR and AG was observed, although a slight deviation from linearity was apparent at low AG, suggesting that chlorophyll fluorometry can be used as the basis of a fair comparison of leaf photosynthetic rates among different maize cultivars.
Xanthophyll cycle and light stress in nature: uniform response to excess direct sunlight among higher plant species
It is concluded that transient diurnal changes in intrinsic PSII efficiency in nature are caused by changes in the efficiency with which excitation energy is delivered from the antennae to PSII centers, and are thus likely to be purely photoprotective.
