| Abstract | In the present study, we investigated the effects of salinity stress, one of the main stress in polluted water bodies, on the photosynthetic activity of Wolffia arrhiza. High salinity stress (1-4%) significantly decreased photosynthetic CO2 assimilation activity, while the chlorophyll a, chlorophyll b and carotenoid contents were not affected after treatment with salinity stress for 24 h. The fluorescence yields at phases J, I and P were clearly decreased by salinity stress above 1%, and the addition of DCMU to the control resulted in the transformation of an O-J-I-P ris e into an 04 rise. Salinity stress decreased the quantum yield of primary photochemistry (phi Po), the quantum yield of electron transport (phi Eo) and the efficiency per trapped excitation (Psi o) in Wolffia arrhiza simultaneously; the number of active PSII reaction centers per excited cross section (RC/CS), the total number of active reaction centers per absorption (RC/ABS) and the performance index of PSII (PIABS and PICS) were also reduced by salinity. These results indicated that the effects of salinity stress on the photosynthesis of Wolffia arrhiza may function by the inhibition electron transport and inactivation of the reaction centers, but the inhibition may occur in the electron transport pathway at the donor and acceptor sides of PSII in Wolffia arrhiza, which is different to that of salt-resistant plants. |
