“…Gouveia-Neto et al (51) tried to use the ratio of red (around 685 nm) and infrared (around 735 nm) ChlF to study the effect of salt stress on the growth process of physicnut (jatropha curcas) grain oil plants. The results indicated that salinity played a minor role in the chlorophyll concentration in leaf tissues for NaCl concentrations in low (25 to 200 mM) range.…”

In the photosynthesis process, part of the absorbed photon energy in photosystem II (PSII) may be reemitted as chlorophyll a fluorescence (ChlF). Environmental and plant physiological changes affect the emission of ChlF, which makes ChlF a potentially useful tool to sense these changes. Volumes of research on ChlF are published each year and some published work has been controversial. To facilitate the application of ChlF, it is important to have a holistic picture of the field. This review summarizes ChlF applications published in the last 10 years.

“…Therefore, fluorescence kinetic parameters have been used to determine photosynthetic traits successfully. Laser-induced fluorescence spectrum analysis is a specific technique that provides a new approach to monitor vegetation physiology remotely (Gouveia-Neto et al 2011;Utkin et al 2014). Leaves have two fluorescence emission peaks located in the 685 nm of the red region (LD 685 ) and the 740 nm of the far-red region (LD 740 ) (Buschmann 2007), which are closely related to the chlorophyll content (Chl t ) (Kalmatskaya et al 2016;Nyachiro et al 2001).…”

Chlorophyll fluorescence (ChlF) has been used to understand photosynthesis and its response to climate change, particularly with satellite-based data. However, it remains unclear how the ChlF ratio and photosynthesis are linked at the leaf level under drought stress. Here, we examined the link between ChlF ratio and photosynthesis at the leaf level by measuring photosynthetic traits, such as net CO 2 assimilation rate (A n), the maximum carboxylation rate of Rubisco (V cmax), the maximum rate of electron transport (J max), stomatal conductance (g s) and total chlorophyll content (Chl t). The ChlF ratio of the leaf level such as maximum quantum efficiency of PSII (F v /F m) based on fluorescence kinetics. ChlF intensity ratio (LD 685 /LD 740) based on spectrum analysis was obtained. We found that a combination of the stomatal limitation, non-stomatal limitation, and Chl t regulated leaf photosynthesis under drought stress, while J max and Chl t governed the ChlF ratio. A significant link between the ChlF ratio and A n was found under drought stress while no significant correlation in the control, which indicated that drought stress strengthens the link between the ChlF ratio and photosynthetic traits. These results suggest that the ChlF ratio can be a powerful tool to track photosynthetic traits of terrestrial ecosystems under drought stress.

“…Fluorescence analysis is a widely used high-sensitivity method that is applied in many scientific and technical fields. A viable application of the technique is the analysis of plant state [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. External factors can cause plants stress and make their growth abnormal.…”

“…There are wide experimental data on the fluorescence spectra of various plant species, both stressed and nonstressed, excited at wavelength ranges of 266-635 nm [2,10,11,15,16]. However, a number of points remain to be investigated.…”

Experimental laboratory investigations of the laser-induced fluorescence spectra of watercress and lawn grass were conducted. The fluorescence spectra were excited by YAG:Nd laser emitting at 532 nm. It was established that the influence of stress caused by mechanical damage, overwatering, and soil pollution is manifested in changes of the spectra shapes. The mean values and confidence intervals for the ratio of two fluorescence maxima near 685 and 740 nm were estimated. It is presented that the fluorescence ratio could be considered a reliable characteristic of plant stress state.
