Fig. 3From: Multiple physiological response analyses aid the understanding of sensitivity variation between Microcystis aeruginosa and Chlorella sp. under paraquat exposuresRadar plots of the main OJIP fluorescence parameters following exposure at 5 min, 1 h, 3 h, 5 h, 9 h, and 24 h for Microcystis aeruginosa (a–f) and Chlorella sp. (g–l). The value in the plots is the ratio of the treatment to the control. The descriptions of fluorescence parameters are presented in Table 1Back to article page
