Fig. 9From: In vivo label-free mapping of the effect of a photosystem II inhibiting herbicide in plants using chlorophyll fluorescence lifetimeMean fluorescence lifetime (τ m) plotted as a function of time for treated and untreated Triticum aestivum leaves imaged using multiphoton excitation at 900 nm, see Fig. 8 for corresponding FLIM images. Standard errors are calculated from the pixelwise fit over the field of view shown in Fig. 8 Back to article page
