Abstract: Aluminium toxicity is the major factor limiting crop growth on acid soils,which greatly affects the crop productivity on about 40% cultivated soils of the world and 21% of China.In the past decades,a lot of researches on aluminium toxicity and resistant mechanisms have been doing,and great progress was achieved.This paper dealt with the genetic differences in aluminium tolerance among plants,screening and selecting methods and technologies for identifying aluminium resistance in plants,and physiological and molecular mechanism resistance to aluminium toxicity.Some aspects needed to be further studied were also briefly discussed.

Key words: Plant, Aluminium toxicity, Genetic difference, Physiological and molecular mechanism of aluminium resistance
