Ethylenediurea (EDU) pretreatment alleviated the adverse effects of elevated O3 on Populus alba “Berolinensis” in an urban area

Ethylenediurea (EDU) has been used as a chemical protectant against ozone (O ). However, its protective effect and physiological mechanisms are still uncertain. The present study aimed to investigate the changes of foliar visible injury, physiological characteristics and emission rates of volatile o... Full description

description: Ethylenediurea (EDU) has been used as a chemical protectant against ozone (O ). However, its protective effect and physiological mechanisms are still uncertain. The present study aimed to investigate the changes of foliar visible injury, physiological characteristics and emission rates of volatile organic compounds (VOCs) in one-year-old “ ” saplings pretreated with EDU and exposed to elevated O (EO, 120 μg/m ). The results showed that foliar visible injury symptoms under EO were significantly alleviated in plants with EDU application (     ). Under EO, net photosynthetic rate, the maximum photochemical efficiency of PSII and the photochemical efficiency of PSII of plants pretreated with 300 and 600 mg/L EDU were similar to unexposed controls and significantly higher compared to EO-stressed plants without EDU pretreatment, respectively....
