Evaluation of Copper Oxide Nanoparticles Toxicity Using Chlorophyll Fluorescence Imaging in Lemna gibba
Figure 3
Change of maximal PSII quantum yield (), operational PSII quantum yield (), photochemical (qP) and nonphotochemical fluorescence quenching coefficient (), and the nonphotochemical quenching parameter (NPQ). Different concentrations are indicated by the different symbols on the figure. The error bars indicate the standard deviations calculated on an average of 6 replicates.
