Changes of organic acid exudation and rhizosphere pH in rice plants under chromium stress.

Environmental pollution (Barking, Essex : 1987) - 1 Sept 2008

Abstract excerpt

The effect of chromium (Cr) stress on the changes of rhizosphere pH, organic acid exudation, and Cr accumulation in plants was studied using two rice genotypes differing in grain Cr accumulation. The results showed that rhizosphere pH increased with increasing level of Cr in the culture solution and with an extended time of Cr exposure. Among the six organic acids examined in this experiment, oxalic and malic...
