Aluminum Bound to Plant Cell Walls-Does Staining Give Clues about the Bound Al Species?
Aluminum sensitivity of plant roots can be determined by staining of Al intoxicated roots with dyes such as Eriochrome cyanine R (ECR) , Solochrome cyanine R ( SCR) , aluminon and chrome azurol S ( CAS). Al-treated roots which stain red-purple are considered Al-sensitive, whereas weakly stained roots are considered Al resistant. Nonhydrolyzed Al (i. e. Al3+) in plant cell walls does not form a strong complex with CAS and gives only a pale color. A positive color reaction with CAS in Al-treated plants roots does not only indicate the presence of Al but hydrolysis of bound Al and the hydrolyzed Al may be more toxic than Al3+.
