Abstract: The growth of plant was strongly inhibited in acid soil,and aluminum toxicity was the most important reason.Scientists have done extensive research work on aluminum-stress responses and aluminum-tolerant mechanism of plant for a long time,and have made lots of remarkable progress.In this article,a review about research methods of plant aluminum-stress was made.For material treatment methods of experiment,it introduced field cultivating,pot-planting outdoors,pot-planting indoors,and nutrient solution culture.For aluminum-tolerance identification,it introduced direct-identification methods including toxic symptoms,root relative elongation and so on,indirect-identification methods such as chemical staining and organic acid secretion.In gene research of aluminum-stress,many methods were introduced about gene mapping,gene differential expression,protein differential expression,transgenic techniques,and so on.
