the measuring system, the air temperature was maintained at 30 ± 3 °C, leaf temperature at 28 °C, relative humidity at 50% ± 10%, and CO 2 concentration at 400 μmol·mol −1 . The photosynthetic electron transport rate (ETR) was then estimated from Ф

the lumen (ΔpH) during PSN also senses changes in light, regulates electron transport, and modulates nonphotochemical quenching (NPQ) in PSII ( Foyer et al., 2012 ; Kono and Terashima, 2014 ). The photoprotective xanthophyll cycle is a significant

elevated CO 2 ( Sage, 1994 ). Briefly, Rubisco capacity ( V cmax ), maximum rate of electron transport ( J max ), and A elev / A ambi (the ratio of A of elevated [CO 2 ] grown leaves over A of ambient [CO 2 ] grown leaves) at multiple C i values

necessary to protect themselves from the depletion of the substrate caused by bentazon-inhibited photosynthesis. Melatonin safener. Bentazon competes with plastoquinone for the binding site on the D1 protein, thus blocking electron transport from photosystem

tetraploid induction in our study, can be considered a measure of the quantum efficiency of the electron transport in photosystem II. Negative correlation between photosynthetic rate and ploidy was observed in other works ( Knight et al., 2005 ; Wullschleger

. Decreases in efficiency of PSII often are thought to be caused by an applied stress that has damaged the photosynthetic apparatus. This results in reduced efficiency of light transfer in photosynthetic electron transport ( Maxwell and Johnson, 2000

tomato leaves, but activation of electron transport chain on the PSI side ( Zushi et al. 2012 ). In addition, low temperature inhibited the photosynthetic efficiency and chlorophyll biosynthesis, and reduced the accumulation of dry matter, and ultimately

in the plant’s roots, stem, leaves, and fruits ( Jin et al. 2017 ). When this happens, diuron interrupts the ‘Hill reaction’ of plant photosynthesis by preventing electron transport from the primary acceptor plastoquinone (PQ) to the secondary

), indicating damage to the PSII reaction center complex. F v /F m represents electron transport efficiency and photochemical efficiency in the PSII reaction center. Layne and Flore (1995) reported that continuous lighting significantly reduced F v and F v
