WebApr 11, 2024 · In this paper, PSII photochemical efficiency (Fv/fm) was measured, and the QY values were shown in Fig. 3 after water stress was simulated on each of the groups of test corn. It can be seen that, when there is a greater degree of water stress, the QY value decreases. After the water stress, QY is restored to 92%, 82%, and 74% of the control ... WebApr 13, 2024 · Compared with those of EMW, the PSII photochemical efficiencies (Fv/Fm) and light quantum efficiency (Fq′/Fm′) of em41 were similar in leaf blades, stems, petioles and the fruit interior but were significantly lower in the exocarp (Fig. 5A), indicating that the photosynthetic machinery of light energy absorption and conversion is similar in ... WebPhotosystem II (PSII) thermostability and acclimation effects on PSII photochemical efficiency were analyzed in thirty field grown winter wheat (Triticum aestivum L.) genotypes using prompt chlorophyll a fluorescence kinetics before and after dark heat treatment. rock and roll resumen
