Fig. 11From: Spatial referencing of chlorophyll fluorescence images for quantitative assessment of infection propagation in leaves demonstrated on the ice plant: Botrytis cinerea pathosystemThe 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 midribsBack to article page
