草类植物耐铝性的研究进展

酸土在全世界热带、亚热带及温带地区广泛存在，酸雨的频繁沉降，加速了土壤酸化。酸性土壤中铝毒害是植物生长发育的主要限制因子。笔者综述了国内外关于铝毒害对草类植物生长发育的影响、草类植物耐铝机理以及草类植物耐铝性遗传育种的研究进展。最后分析了目前草类植物耐铝性研究存在的问题，并对草类植物耐铝性研究前景进行展望。

Advance in studies on aluminum tolerance of grass

Acid soil is extensively distributed in the tropical zones,subtropical zones and temperate areas all over the world,and acidification of the soil is frequently accelerated by acid rain.Aluminum-toxicity is a main factor restricting growth and development of plants in acid soil.The aluminum tolerance of grass is reviewed in this paper,including toxicity to growth,resistance mechanisms and the heredity and assessment of grass aluminum resistance.Finally,the problems existing in research on aluminum tolerance of grass was analyzed,and directions for future study are discussed.
