摘要

In the present study, hydroponic experiments were performed to clarify if abscisic acid ( ABA) is involved in modulating Al resistance in soybean. Exogenous ABA and ABA synthesis-inhibitor Fluridone alleviated and aggravated the Al-induced inhibition of root elongation, respectively. Aluminum stress increased the endogenous ABA content in both roots and leaves. Lanthenum only increased the endogenous ABA content in roots. Split-root experiment revealed that only direct contact with Al induced an increase of endogenous ABA, and ABA in the roots not treated with Al seems to be transported to the roots under Al stress. Taken together, ABA-mediated signal transduction might be involved in regulating Al resistance in soybean.
