Low concentration of exogenous abscisic acid increases lead tolerance in rice seedlings

Year: 2009

Type: article

Abstract: The effects of exogenous abscisic acid (ABA) on lead tolerance in rice (Oryza sativa L.) seedlings were investigated. Pre-treatment with 0.1 g m3 ABA for 2 d restricted amount of Pb translocated from roots to shoots, decreased malondialdehyde and H2O2 contents in leaves, and alleviated Pb-induced decrease in plant growth and leaf chlorophyll content. Further, ABA pre-treatment adjusted leaf antioxidative enzyme activities (increased ascorbate peroxidase and catalase activities while decreased superoxide dismutase activity) and so alleviated oxidative stress.
