Sentence examples for maximum fluorescence Fm from inspiring English sources

Chlorophyll fluorescence measurements included initial fluorescence (Fo), maximum fluorescence (Fm) and variable fluorescence (Fv).

QY represents the ratio of variable fluorescence (Fv = Fm − F0) to maximum fluorescence (Fm), with QY = Fv Fm used as a proxy of photochemical quenching efficiency [70].

The results demonstrated that the highest light intensity and the severe water stress decreased maximum fluorescence (Fm), variable fluorescence (Fv /Fm, quantum yield of PSII photochemistry (ФPSII), Chl and photochemical quenching (qP) but increased non-photochemical quenching (NPQ), minimum fluorescence (F0) and Anthocyanin (Anth).

The minimum (F0) and maximum fluorescence (Fm) was measured at the end of a dark-acclimation period (3 min) and the maximum quantum yield (the PSII efficiency) was calculated from Fv/Fm, where Fv is the variable part of fluorescence emission and equal to Fm F0.

A saturation pulse was applied to obtain maximum fluorescence (Fm) in the dark-adapted samples.

The PSII photochemistry in vivo was tested by measuring the initial (F0) and maximum fluorescence (Fm) values in dark-adapted pea and bean leaves.

The J–I phase (at 30 50 ms) is due to the closure of the remaining centers (further reduction of QA and various redox states of temporary maximum of Q A − Q B 2− ) and the I P phase (ends at about 300 500 ms) corresponds to the full reduction of the plastoquinone pool (equivalent to maximum fluorescence level Fm).

Saturating pulses were applied to obtain the maximum fluorescence yield (Fm).

Maximum fluorescence level (Fm) was measured after 0.5 s saturating pulse at 4,000 μmolm−2s−1.

Light adapted maximum fluorescence level (Fm') was measured with a second saturating pulse (0.5 s, 4,000 μmolm−2s−1).

The ratio of variable to maximum fluorescence (Fv/ Fm) was used as an indicator of the maximum quantum efficiency of photosystem II.
