水稻耐盐/碱性鉴定评价方法

土壤盐/碱化是盐/碱稻作区水稻生产稳定发展的主要限制因素.为了提高水稻耐盐/碱性,扩大水稻种植面积,减轻盐/碱胁迫导致的水稻减产,许多学者广泛开展了水稻耐盐/碱性的基因型差异、生理生化、遗传及定位等研究,并取得了显著成绩.但国内在耐盐/碱性鉴定评价方法方面还缺乏统一标准,这影响着水稻耐盐/碱性研究的深入开展.本文阐述了国内外至今所采用的水稻耐盐/碱性鉴定方法、耐盐/碱指标和分级标准等,以期为我国水稻耐盐/碱性鉴定评价技术规范的制定以及水稻耐盐/碱性种质资源鉴定、生理生化分析和遗传育种提供参考依据.

Methods of Characterization and Evaluation of Salt or Alkaline Tolerance in Rice

Salt or alkaline soil is the main restricting factor of steady steady development in rice production. In order to improve salt or alkaline tolerance in rice, expand plant area and reduce low product caused by salt or alkaline stress, a lot of researches have conducted studies on genotype diversity, physiology and biochemistry, genetics and gene mapping of salt or alkaline tolerance in rice. But there is not a standard method for characterization and evaluation on salt or alkaline tolerance in china, which affects further development salt or alkaline tolerance of rice. This paper describes the methods of characterization and evaluation index and grading standard of salt or alkaline tolerance of rice in the world, providing the basis for standard methods of characterization and evaluation of salt or alkaline tolerance in rice, characterization of rice germplasm, physiologic biochemistry analysis and genetic breeding.
