Study on the characteristic curve of laser-induced delayed luminescence in leaves of Scindapsus

Abstract At room temperature, we studied the delayed luminescence characteristic curves of leaves Scindapsus in darkroom and continuously irradiate at different wavelengths. The results show that decay stimulated emission photons induced by pulsed laser has a typical hyperbolic trend with delay time, goodness fitted curve can reach 99.9%. initial photon intensity I (0) time τ are closely related to environment physiological activities plants. In dark room, it was found for picked decreased, while potted remained almost unchanged. laser-induced accurately reflected process degree plant wilting. For irradiated wavelength 520 nm 400 nm, respectively, change parameters reflects selective absorption light Compare condition having without, metabolites photosynthesis respiration plants, which leads greatly changes time. be used as an important parameter measure state
