Abstract

The characters of ultra-weak biophoton emission (UBE) of rice seeds during the initial imbibition period (0-1 hour) were observed with high sensitive single-photon-counting equipment. The results showed that the shorter the seed store time, the higher the intensity and the increase rate of the UBE in the early imbibition period (0-10 minus). It was concluded that the store time of rice seeds could be judged from their UBE characters during the early imbibition period, which might be a way to examine new and aged seeds. In addition, there were differences in rise rate, peak value and attenuation tendency of UBE among new seeds of different strains during the early imbibition period. It indicated that such characters of UBE might be quantitative indexes to identify new rice seeds.
