Introduction to Fluorescence Transients

The fast chlorophyll a fluorescence transients were measured after 2 and 4 weeks of fumigation, as well as in control plants, and analyzed by the JIP-test, which is a non-destructive, non-invasive, informative, very fast and inexpensive technique used to evaluate the changes in photosynthetic efficiency.

In this study, five Mn concentrations (0, 12, 24, 36, and 48 mM) were used, and the toxicity of Mn on PSII behavior in leaves of Ligustrum lucidum was investigated using in vivo chlorophyll fluorescence transients.

The cessation of H+ influx across the plasma membrane by eliciting the action potential and by adding NH4Cl into the medium greatly enhanced the amplitude of cyclosis-mediated fluorescence transients.

OJIP chlorophyll fluorescence transients suggest that in C.

They thus suggest that two simple, non-invasive and rapid methods, namely, the analysis of OJIP fluorescence transients and the measurement of CCI, can be used to screen the effect of elevated O3 on biomass of canola plants.

And a significant decrease in the P-step level of the fluorescence transients OJIP curves of four populus species after 7 days of treatment was observed.

In this boxcar integration, the time resolution of fluorescence transients is limited solely by the laser pulse length and is independent of the detector IRF.

The acute toxicity of Cd in soil to the photosynthetic capacity of Hybrid Pennisetum was evaluated using gas exchange parameters, A/Ci curves, light response curves, and chlorophyll a fluorescence transients after exposure to elevated Cd concentrations (0, 10, 20, 50, 70, and 100 mg kg−1) for a 3-month period.

We acquired over 700,000 chlorophyll fluorescence transients and spectral measurements under semi-field conditions in four crop species including 28 genotypes.

The current study determined differences in fast chlorophyll fluorescence transients and changes in radiation reflectance in sporotrophophylls and nest leaves after one and seven days of HL.

Therefore, several spiking activity reconstruction methods have been introduced, where most of them are limited in dealing with issues such as variability in the kinetics of fluorescence transients, fast processing of long-term data, measurement noise and high firing rates.

We used growth measurements and determined the photosynthetic parameters based on chlorophyll fluorescence transients in the algal cells exposed to different concentrations of the three AgNMs.

To uncover any detriment of high temperature from photosynthesis on Cinnamomum camphora, the effects of high temperature stress on chlorophyll fluorescence transients, gas exchange rate, and water use efficiency in the plants treated with high temperature at 25℃ (the control), 35℃ and 45℃, respectively, were studied, and one-way analyses of variance was performed to analyze the effects of high temperature.

The spectroscopic and magnetic properties of the Yb3+ ions dissolved in the glass and, presumably, in the nanocrystallites, were investigated by absorption and emission spectroscopies (including anti-Stokes emissions from Tm3+ and Er3+ impurities), fluorescence transients and magnetic susceptibility measurements.

These changes compared well with the gradually increasing membrane permeability, as testified by the gradual acceleration of the decay of flash-induced electrochromic absorption changes and characteristic changes in the kinetics of fast chlorophyll a-fluorescence transients; all variations were much less pronounced in the NaCl-based medium.

Furthermore, when examining the encoding of behavioral state variables by nervous system, filtering by the reporter kinetics will favor the interpretation that fluorescence transients encode integrals of measured variables as opposed to the variables themselves.

To further verify the reliability of PIabs, four genotypes were grown under low temperature gradient conditions and their morphological indexes, chlorophyll content, total antioxidant capacity, fluorescence transients (OJIP transients), leaf cell ultrastructure, and gene expression were measured.
