| 摘 要： | 在模拟酸雨条件下，对樟树的种子萌发和幼苗生长进行了观测。结果表明，ｐＨ２．０的模拟酸雨严重地抑制种子的萌发，伤害了幼苗的叶片，降低了叶绿素的含量，增加了细胞的透性，使叶汁液的土壤酸化，从而阻碍了幼苗的生长。

| Abstract: | Seed germination and seedling growth for camphor tree were moni-tored under exposure the seed and seedling to a simulated acid rain,The pH 2.0 acid treatment inhibited seedgermination and seedling growth by damaging foliage,decreasing chlorophyll contents, increasing leaf cell perineability,and acidifying leaf sap and the soil. Whereae pH 3.5 acid treatment increased the biomass in spite of some negative effects on seedling growth.No significant treament effects were observed at pH values of 5.0 and 6.0. |
