Abstract

The images of germinating mung beans show that the light-induced biophoton emission is detectable after 40 minutes of light exposure. The longer the time in which seedlings were cultured under light, the stronger the biophoton emission was, and stronger seedling produced stronger emission. As for the light emission in the investigated plants, the strongest parts are the shoot apex and newly-formed leaf, followed by hypercotyl, cotyledon and hypocotyl, and roots are the weakest one. In respect to UBE of leaves at different developmental stages, mature leaf is strongest, the maturing leaf and senescing leaf are weaker, and the young leaf is weakest. Moreover, significant UBE was not observed either in extract of chlorophyll or in quickly-boiled-to-death young leaves. The UBE spectrometry of leaves and chlorophyll are characterized by similar features.
