Fv/Fm is a normalized ratio created by dividing variable fluorescence by maximum fluorescence. It is a measurement ratio that represents the maximum potential quantum efficiency of …

In this research, a least-squares support vector machine (LSSVM) model was developed to explore whether Fv / Fm can be determined from ChlF induction curves measured without …

Fv / Fm is an estimate of the maximum quantum efficiency of PSII reaction centers. This ratio is calculated from two parameters: Fo and Fm. Fo is the fluorescence level of a dark-adapted …

Abstract: Although results of chlorophyll fluorescence (CF) measurements in nursery seedlings are becoming widely reported in the literature, the theory, terminology, and interpretation of …

2024年7月1日 · Fv/Fm indicates the maximum quantum yield of photosystem II (PSII) in plants, and it is a ratio used to evaluate the efficiency of photosynthesis in these organisms.

2013年8月3日 · Chlorophyll fluorescence is one of the most popular techniques in plant physiology because of the ease with which the user can gain detailed information on the state …

Fv / Fm is a ratio that indicates about the quantum efficiency of photosystem II. PI (performance index) indicates about the efficiency of both photosystems I and II.

2009年6月17日 · The operational efficiency (Fq′/Fm′) of PSII can be viewed as the product of two other fluorescence parameters: Fv′/Fm′, the maximum quantum efficiency of PSII …

The fluorescence parameters FV/FM, FV'/FM',qp,qN, NPQ, and phiPS II were originally developed to extract information from the fluorescence signals of higher plants.

It is strongly recommended to determine, in addition to the classical fluorescence parameters, via the PAM fluorometer also the Chl fluorescence decrease ratio R Fd (F d /F s), which, when …
