The photosynthetic characteristics of under high temperature stress were studied in a subtropical forest tree seedling, Ficus concinna. Net photosynthetic rate decreased to 21% of the control after high temperature stress, and thus the absorption of photon energy exceeded the energy required for CO₂ assimilation. The efficiency of excitation energy capture by open PSII reaction centers (Fv´/Fm´), photochemical quenching (qP), and the electron transport rate (ETR) were significantly lower after high temperature stress. These results indicated that high temperature stress causes a decrease in the photochemical efficiency of PS II, thereby depressing the linear electron transport and photosynthetic rate. Nevertheless, the non photochemical quenching (qN) was significantly higher under such conditions, thus helping to dissipate excess photon energy non-radiatively.
