Ultra-weak photon emission and its mechanism during tomato ripening

摘要

Experiments were carried out using the tomato (Lycopersicon esculentum) stored at 28℃ and 4℃, at the same time, the spontaneous ultra-weak photon emission (UPE), delayed luminescence (DL), ethylene releasing, respiratory intensity, chroma main wavelength and chlorophyll content were detected. It was found that: The curve of the spontaneous UPE is just consists with respiratory intensity at 28℃ and relate to chlorophyll content variation. The experiment data were given guide line to noninvasive test maturity, DL data were dealt with curve fitting and compared with coherent theory.
