据报道,在总照射量为一定值时,照射量率是影响最终生物效应的重要因素之一。使用某一辐射量的速率对于所得结果,常有显著的定性及定量的效应。因此,选用适宜的照射量率是提高辐射诱变效率的一项重要措施。但直到最近以农作物特别是以水稻为试验材料研究适宜照射量率的报道还不 It has been reported that the exposure rate is one of the important factors that affect the final biological effect when the total exposure dose is a certain value. The rate at which a certain amount of radiation is used often has significant qualitative and quantitative effects on the results obtained. Therefore, the selection of the appropriate dose rate is to improve the efficiency of radiation mutagenesis is an important measure. However, until recently, the reports on appropriate irradiation rates using crops, especially rice as test materials
