Background on the various steps of photosynthesis is available in several publications [3,4].
WebSep 4, 2024 · Measuring chlorophyll a fluorescence is a rapid and non-invasive probe of plant photo-chemistry, and the technique has been used for decades to monitor a wide range of biotic and abiotic stresses of algae and higher plants (Kalaji et al. 2024; Guo and Tan 2015; Brestic and Zivcak 2013 ). WebChlorophyll fluorescence was measured with a chlorophyll fluorimeter (IMAGIM-PAM M-series, Heinz Walz, Effeltrich, Germany) during the acclimatisation period of stevia plants to ex vitro conditions, at 2, 7, 14, 21, and 28 days of the initiation of the acclimatisation period. After a dark incubation period (20 min), the minimum and the maximal ...
WebChlorophyll a fluorescence depicts the emission of photons and transfer of electrons in photosynthetic reaction center, the redox status of donor side and acceptor side of photosynthetic electron transport chain, and primary dynamics of plant photosynthesis (Banks, 2024, Dayan et al., 2012). WebChlorophyll molecules absorb photosynthetic active radiation (PAR). The resulting excitation energy is dissipated by three competing pathways at the level of photosystem: (i) photochemistry (and, by extension, photosynthesis); (ii) regulated and constitutive thermal energy dissipation; and (iii) chlorophyll-a fluorescence (ChlF).
