Summary of multispectral lifetime point-probe measurements in Triticum aestivum. The different spectral detection channels are represented by CH1, CH2, CH3 and CH4 and are separated by black dotted vertical lines. Untreated plant samples are named in the format p(n)l(m), where n is the plant number and m is the leaf number. Treated plants are named tp(n)l(m). The weighted mean fluorescence lifetime (τ _m) calculated for each sample is plotted in the respective spectral channels
