在湖南省林业科学院林场苗圃内对香樟（Cinnamomum camphora）、深山含笑（Michelia maudiae）、栾树（Koelreuteria paniculata）、鹅掌楸（Liriodendron chinense）4个树种的1年生幼苗进行铅胁迫试验,设定Pb2＋浓度为对照、50mg/L、400mg/L、800mg/L、1600mg/L共5个水平,每一处理重复3次,研究不同铅浓度对4种行道树幼苗叶片过氧化物酶（POD）和超氧化物歧化酶（SOD）的影响,得出苗期试验结果。

Pb stress experiment were carried out on 1-year-old seedlings of 4 species of street tree including Cinnamomum camphora,Michelia maudiae,Koelreuteria paniculata and Liriodendron chinense in the experimental nursery of Hunan Academy of Forestry.The Pb2＋ concentration was chosen as the control （no Pb2＋）,while 50 mg/L,400 mg/L,800 mg/L and 1600 mg/L were set for the experiment,each with 3 replicates.The experiment was done to study the effect of different Pb concentrations on POD and SOD of leaves of the 4 species of street tree.The experiment results were finally obtained for the effect.
