小麦富硒研究进展

摘要

目前，硒元素营养失衡已严重影响人类健康，中国约7亿人口生活在低硒地区，而小麦作为人们的主要食物，其籽粒中硒元素含量普遍较低。通过土壤施用和叶面喷施硒肥等途径来增加小麦籽粒内部硒元素累积量，进而改善人体硒营养水平被认为是经济有效的手段，这也引起了国内外学者的广泛关注。本文概述了小麦对硒的吸收、转运和分布特点，提高小麦籽粒硒含量的途径、影响因素，富硒小麦的加工工艺及产业发展中存在的问题，并对今后富硒小麦产业的研发做出了展望。%At present,human health has been seriously affected by the unbalance of selenium (Se)nu-trient.About 700 million people live in low Se areas in China.Wheat (Triticum aestivum L.)as the staple food of people,its grain Se content is generally low.Through increasing the soil effective selenium and /or by foliar application of selenium fertilizer,the grain Se content can be dramatically enhanced.These ways have been considered to be economic and effective means to improve human Se nutritional level and have caused the wide attention of scholars at home and abroad.The characteristics of the absorption,transportion and distribu-tion of Se in wheat,the ways and possible influencing factors to improve wheat grain Se content,the Se -en-riched wheat processing technology and the problems and prospects in the development of Se -enriched wheat industry were summarized in this paper.
