Application Status of Chlorate in Nitrate Nitrogen Research of Rice
Chlorate treatment is one of successful ways to screen rice varieties with nitrogen efficiency and high tolerance to low nitrogen.The nitrogen use efficiency(NUE)of rice can be effectively determined by the study of the strength of sensitivity to chlorate.This review summaries the progress of the application of chlorate in nitrate nitrogen utilization research in rice including the appraisal principle for chlorate,identification techniques and evaluation indices of rice chlorate sensitivity,screening of rice germplasms with low nitrogen efficiency and high nitrogen tolerance based on chlorate,and the use of chlorate in the investigation of nitrogen-related genes.Moreover,we analyze the existing problems such as shortage and limitation of chlorate in nitrogen research,which in order to provide the basis for its application in breeding for high NUE rice cultivars and exploring nitrogen regulation mechanism.
