Effect of Temperature Variation on Maximum Fluorescence (Fm) in Acer Campestre

This poster is about the controlled exxperiment I performed inside the lab by manipulating the temperature values for the plant samples inside a water bath and observing their Fv/Fm values. The pupose of this work was to evaluate the heat tolerence utilizingchlorophyll a fluorescence, Leaf impairment is gauged either through the temperature-sensitive augmentation of the reduction in the variable to maximum fluorescence ratio (Fv/Fm), indicative of potential photosystem II (PSII) efficiency. Chlorophyll a fluorescence emission is influenced not solely by the physiochemical characteristics of PSII but also by leaf optical properties, including light absorption levels by leaves and PSII reaction centres. In instances where a stressor impacts leaf optical properties independently of physiochemical traits, such as under high temperatures (Takahashi and Badger, 2011), the utilization of fluorescence ratios (Fv/Fm) over absolute values (F0) is recommended, as ratios are prone to nullify potential inaccuracies (Baker, 2008).
