中文摘要：铝害是酸性土壤中作物生长发育的一个主要限制因素。作物耐铝性在种间和品种间存在明显差异。目前有关作物铝毒害及不同耐铝性基因型差异的机理尚不十分清楚,限制了相关育种和栽培工作的开展。近几年来,世界各国针对作物的铝毒害及其耐铝机制进行了大量的研究,并取得了较大进展。本文综述了目前有关铝对麦类作物的毒害及其耐铝机理的研究成果,并简要讨论了今后的研究方向。

外文摘要：Aluminum toxicity is a major limiting factor for crops grown in acid soils. In tact, acidification could bring about many other changes of physical and chemical properties in soil, which in turn also affect plant growth and development. On acid soil, some nutrients, such as P, Ca and Mg are usually deficiency, while others, such as Mn and B could attain very high available concentration toxic to plants. Similarly, the bio-availability of some heavy metals e. g. Cd increases markedly, causing toxicity to the plants. Plant species and genotypes within species greatly differ in tolerance to acidic stress. However, there is little information about the mechanisms of aluminum toxicity and the genetic difference in aluminum tolerance of plants, thus exposing a constraint on carrying out relevant breeding and cultivation programs. In the past decades, many researches had been carried out on aluminum toxicity and tolerant mechanism in plants, and great progress was achieved. This paper reviewed the studies on aluminum toxicity and tolerance in wheat and barley. The main fields and projects for further research are also briefly discussed.
