Effects of far-red light on fluorescence induction in infiltrated pea leaves under diminished ΔpH and Δφ components of the proton motive force.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Chlorophyll fluorescence induction curves induced by an actinic pulse of red light follow different kinetics in dark-adapted plant leaves and leaves preilluminated with far-red light. This influence of far-red light was abolished in leaves infiltrated with valinomycin known to eliminate the electrical (Δφ) component of the proton-motive force and was strongly enhanced in leaves infiltrated with nigericin that abolishes the ΔpH component. The supposed influence of ionophores on different components of the proton motive force was supported by differential effects of these ionophores on the induction curves of the millisecond component of chlorophyll delayed fluorescence. Comparison of fluorescence induction curves with the kinetics of P700 oxidation in the absence and presence of ionophores suggests that valinomycin facilitates a build-up of a rate-limiting step for electron transport at the site of plastoquinone oxidation, whereas nigericin effectively removes limitations at this site. Far-red light was found to be a particularly effective modulator of electron flows in chloroplasts in the absence of ΔpH backpressure on operation of the electron-transport chain.
