Stems emitted 650∼700 nm of fluorescence at excitation wavelengths ranged from 350 nm to 650 nm because of the presence of chlorophyll [ 14 ]. However, emission from intact cuticle is too weak to detect … By exciting chlorophyll a fluorescence at a lower wavelength, the ratio of chlorophyll fluorescence emission at 705 ± 10 nm and 735 ± 10 nm can provide a linear relationship of chlorophyll content when compared with chemical testing.
