摘要

见光培养40min后的绿豆幼苗即可探测到明显的延迟发光;见光时间越长,光诱导的延迟发光强度也越强。从绿豆和花生幼苗的超弱发光图象来看,生长健壮的幼苗发光较强。其中茎尖和新生幼叶的延迟发光最强,上胚轴、子叶和下胚轴弯钩较强,下胚轴伸长部分次之,根部发光最弱。

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.
