The fluorescence parameter NPQ value changes in C3 and CAM common ice plant leaves. NPQ is computed at three locations (a, b) and along the line distance L1 and L2 (c–f) depicted in Fig. 9a, b. The measurement points are: (1) mesophyll at the site of inoculation, (2) mesophyll without injury, and (3) midrib; c, d mesophyll at the site of inoculation; e, f midribs
