摘　　要：氯酸盐处理是筛选耐低氮和氮高效种质的有效手段之一,通过研究水稻对氯酸盐的敏感性强弱可有效预测其氮利用效率(NUE)。本文阐述了氯酸盐在水稻硝态氮利用研究的进展,主要包括氯酸盐的鉴定原理、水稻氯酸盐敏感性鉴定方法和评价指标、基于氯酸盐的耐低氮和氮高效的水稻种质资源筛选以及氯酸盐在氮相关基因研究的运用等几个方面,同时指出氯酸盐在氮利用研究中存在的不足和局限性等,为氯酸盐鉴定在高NUE水稻育种和氮调控机制研究中的应用提供参考。Chlorate treatment is one of successful ways to screen rice varieties with nitrogen efficiency andhightolerance to low nitrogen.The nitrogen use efficiency(NUE)of rice can be effectively determined by thestudyof the strength of sensitivity to chlorate.This review summaries the progress of the application of chlorateinnitrate nitrogen utilization research in rice including the appraisal principle for chlorate,identification techniquesand evaluation indices of rice chlorate sensitivity,screening of rice germplasms with low nitrogen efficiencyandhigh nitrogen tolerance based on chlorate,and the use of chlorate in the investigation of nitrogen-relatedgenes.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 exploringnitrogen regulation mechanism.
