It was shown that the root elongation was inhibited and the malonaldehyde content in root apices and the antioxidase activities of root apices were increased under Al stress (30 μmol/L), while the effects of Al were significantly alleviated by the addition of Si (1.4 mmol/L). Moreover, both Si added before Al treatment and Si added simultaneously with Al treatment could alleviate these effects. On the other hand, the cultivar of Seca was shown to be more sensitive to Al than other cultivars in the absent of Si, while Al-resistance distinction among the cultivars of stylosanthes turned to be non-significant in the present of Si in the pre-cultured solution or both pre-cultured and Al-treatment solutions.
