Abstract

With a high sensitivity ultraweak bioluminescence imaging system, we have obtained the emission spectra of ultraweak bioluminescence from Chinese cabbage leaf and isolated chloroplasts during the period 20 - 85 s after the cessation of illumination. Emission spectra demonstrate that chloroplast is the main origin of ultraweak bioluminescence from leaf. We suggest that the emission of leaf may be related to charge recombination in reaction center of photosystem II and deexcitation of antenna pigments.
