N2 - Chlorophyll fluorescence (ChIF) is emitted in the range of 640-850 nm, with two local maxima (peaks) - at around 685 and 740 nm, respectively. The spectral shape and peak positions of the ChlF spectrum carries information of plant photosynthetic status. A preliminary study based on experimental data about the ChlF peak positions under different conditions, such as species, chlorophyll content, photosynthetically active radiation, irrigation conditions, are presented. The results show that herbaceous and woody plants have different distributions of the ChlF peak positions. The far-red peak positions shift to longer wavelength when chlorophyll content increases, while the red peak positions do not show a clear changing pattern. Besides, incident PAR levels also have a noticeable effect on the shift of the ChlF peak positions. Finally, the far-red peak positions span a broader distribution under drought-stress condition.
