| Abstract: | Made in this paper is a general review on following topics: (1) factors of soil acidification and process of aluminum activation; (2) the symptoms of Al-injured plants, the resistance of paints to aluminum and the relationship between aluminum speciation and phytotoxicity; (3) the external factors affecting aluminum toxicity expression, such as P, Ca and organic matter; and (4) some mechanism of Al phytotoxicity relating to biomembrane, Calmodulin DNA and ATP. Finally, some ameliorative measurements of Al-toxic soils have also been discussed. |
