摘要: The pollution of the environment by rare earth elements (REEs) causes deleterious effects on plants. Peroxidase plays important roles in plant response to various environmental stresses. Here, further understand overall peroxidase REE stress, terbium ion (Tb3+) activity and H2O2 lignin contents leaves roots horseradish during different growth stages were simultaneously investigated. results showed that after 24 48 h Tb3+ treatment, decreased, while increased. After a long-term (8 16 days) treatment with Tb3+, these also observed roots. analysis changes revealed not only reactive oxygen species scavenging but cell wall lignification under stress. These closely related dose duration horseradish.
