Control of steady‐state photosynthesis in sunflowers growing in enhanced CO₂

Plant, Cell & Environment, 1994
ABSTRACTControl coefficients were used to describe the degree to which ribulose bisphosphate carboxylase/oxygenase (Rubisco) limits the steady‐state rate of CO2 assimilation in sunflower leaves from plants grown at high (800 μmol mol−1) and low (350 μmol mol−1) CO2.

Effect of redox state on the dynamics Photosystem II during steady-state photosynthesis in eucaryotic algae

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 1988
Abstract Using a pump and probe-flash technique we simultaneously measured changes in fluorescence yields (ΔΦ) and the yield of oxygen produced by the pump flash ( Y ) during steady-state photosynthesis in continuous background light in two species of eucaryotic algae, Chlorella pyrenoidosa , a chlorophyte, and Chaetoceros gracilis , a diatom.

Integrated photosynthesis during fluctuating irradiance is correlated with steady-state photosynthesis for rice grown in field environments with elevated CO2 and temperature

Journal of Experimental Botany
Abstract Photosynthesis under fluctuating irradiance is understudied, especially its response to elevated CO2 and temperature in field environments. We measured photosynthesis after a single-step irradiance change and during a series of lightflecks for rice (Oryza sativa L.) grown under combinations of two CO2 levels (ambient and ...

Steady State Photosynthesis in Intact Plants as Analyzed by Chlorophyll Fluorescence and Far-Red Spectroscopy

1988
We relate photochemical and non-photochemical (‘high-energy’) guenching of in vivo fluorescence and the redox state of P700 (as analyzed by far-red spectroscopy) to electron transport during steady state assimilation. From the data we derived expressions which provide a basis of conducting measurements of the apparent guantum yield and the rate of ...

Measurement of Photochemical and Non-photochemical quenching: Correction for turnover of PS2 during steady-state photosynthesis

1990
An empirical expression that could be used to predict the quantum efficiency of PS 2 during steady-state photosynthesis from measurements of chlorophyll fluorescence quenching was proposed by Weis and Berry [1], and several subsequent papers have presented evidence corroborating this approach [2–7].
