But we put also emphasis on some of the parameters derived from analysis of the induction phase of maximal ChlF, notably because they could be used to assess damage to photosystem II. There are three energy pathways for the absorbed light energy by photosystem II (PSII) of plant leaves: photochemical reaction, heat loss, and chlorophyll fluorescence (ChlF) emission [].According to the law of energy conservation, there is a competitive relationship between these three pathways. As chlorophyll fluorescence is a measure of re-emitted light (in the red wavebands) from PSII, naturally this means that any ambient light can interfere with the measurement of fluorescence and thus many early systems had to be used in darkness and/or highly controlled light environments. Fluorescence can be used in plant phenotyping and breeding programs to monitor biotic and abiotic stresses including mineral deficiencies, soil salinity, and pathogenic diseases. Here, we examined the link between ChlF ratio and photosynthesis at the leaf level by measuring photosynthetic traits, such as .

These excited electrons are passed along and can be used in photosynthesis, however, very rarely is 100% of this energy used in this manner. Thus, the SIF wavelength range up to 700-720 nm is heavily affected by chlorophyll reabsorption, reducing the red peak at 685 nm (Gitelson et al., 1999). Solar-induced chlorophyll fluorescence (SIF) is a signal emitted directly from the core of photosynthetic machinery. Decreases of this index are indicative of the reduction of photosystem II (PSII) efficiency, namely photoinhibition. Download Citation | On Nov 28, 2003, G.H. 1 Chlorophyll molecules in plant leaves are organized into so-called photosynthetic units, macromolecular complexes that contain many chlorophyll molecules and 'reaction centers' that process the absorbed energy (see Figure 1).In these centers, the pigment molecules act as 'antennas .

(Heinrich Heine University, Dusseldorf, Germany); Weis, E.; 39. While these primary processes are interesting in their own right, the role that is played by PSII in photosynthetic electron transport and thus photosynthesis,… Chlorophyll a fluorescence As mentioned earlier, in addition to primary photochemistry, photosynthetic organisms lose some energy as heat (internal conversion) and as light (fluorescence). chlorophyll fluorescence efficiency (hereinafter referred to as CFE) as well as for daily primary productivity (MOD27, parameter 2602) which will be a post-launch product. As fluorescence is an indicator both the amount of chlorophyll and the rate of photosynthesis, higher order products will be based on FLH. Salt stress is one of the main stressors limiting plant growth and yield. Chlorophyll a fluorescence (ChlF) has been used for decades to study the organization, functioning, and physiology of photosynthesis at the leaf and subcellular levels. 4. But we put also emphasis on some of the parameters derived from analysis of the induction phase of maximal ChlF, notably because they could be used to assess damage to photosystem II. Light energy absorbed by chlorophyll molecules in a leaf can undergo one of three fates: it can be used to drive photosynthesis (photochemistry), excess energy can be dissipated as heat or it can be re‐emitted as light—chlorophyll fluorescence. 'Chlorophyll fluorescence data as a proxy of biomass in situ must clearly be interpreted with caution.' Fluorescence and photosynthesis: the story so far Following from the paper of Kautsky & Hirsch (1931), Abstract. The basis of photosynthetic acclimation and its optical signals is presented, the physical and physiological basis of ChlF is introduced from the molecular to the leaf level and beyond, and PAM and SIF methodology are introduced. The principle underlying chlorophyll fluorescence analysis is relatively straightforward.
