Ultra-weak bioluminescence and vigour of irradiated rice

Abstract

Detection of the irradiation dose and the vigour of irradiated rice based on ultra-weak luminescent analysis is one of the analytical detection methods. Rough rice and head rice flour were used in this research for ultra-weak luminescent analysis. The bioluminescent intensity of rough rice was different at irradiation dose after different storage time, and the trend was consonant with the germination rates of irradiated rough rice. The bioluminescent intensity and germination rates of irradiated rough rice at irradiation dose after different storage time were due to the effect of the rice embryo that affected by irradiation, which had self-repair during storage. As a result, the ultra-weak luminescent analysis with rough rice cannot used to detect the irradiation dose of irradiated rice, but it can be used to detect the vigour of irradiation rice. Experimental results show that the irradiation dose has a highly significant effect on the bioluminescent intensities of rough rice flour when cane sugar was added.
