AB  - Delayed fluorescence (DF) from photosystem II (PSII) of plants can be potentially 
      used as a biosensor for the detection of plant physiological status and 
      environmental changes. It has been analyzed mainly in the time domain. 
      Frequency-domain analysis through Fourier transform allows viewing a signal from 
      another angle, but the usefulness of DF spectra has not been well studied. In 
      this work, experiments were conducted to show the differences and similarities in 
      DF spectra of different plants with short pulse excitation. The DF spectra show 
      low-pass characteristics with first-order attenuation of high frequencies. The 
      results also show that the low-frequency components differ while the 
      high-frequency components are similar. These may imply the potential usefulness 
      of Fourier spectra of DF to analyze photoelectron transport in plants and 
      classify samples.
