RT Journal Article T1 Imaging of chlorophyll a fluorescence in natural compound-induced stress detection A1 Sanchez Moreiras, Adela Maria A1 Graña Martinez, Elisa A1 Reigosa Roger, Manuel Joaquin A1 Araniti, Fabrizio K1 2417 Biología Vegetal (Botánica) K1 2417.19 Fisiología Vegetal K1 2302.25 Fotosíntesis AB Imaging of chlorophyll a fluorescence (CFI) represents an easy, precise, fast and noninvasive technique that can be successfully used for discriminating plant response to phytotoxic stress with reproducible results and without damaging the plants. The spatiotemporal analyses of the fluorescence images can give information about damage evolution, secondary effects and plant defense response. In the last years, some studies about plant natural compounds-induced phytotoxicity have introduced imaging techniques to measure fluorescence, although the analysis of the image as a whole is often missed. In this paper we, therefore, evaluated the advantages of monitoring fluorescence images, presenting the physiological interpretation of different possible combinations of the most relevant parameters linked to fluorescence emission and the images obtained PB Frontiers in Plant Science SN 1664462X YR 2020 FD 2020-12-21 LK http://hdl.handle.net/11093/2342 UL http://hdl.handle.net/11093/2342 LA eng NO Frontiers in Plant Science, 11, 583590 (2020) NO Ministerio de Ciencia, Innovación y Universidades | Ref.
