| 摘 要： | 采用开顶式气室装置研究5种臭氧(O_3)浓度对6种绿化树种,即杨树基因型‘546’(Populus deltoides cv.‘55/56’×P.deltoides cv.‘Imperial’)和‘107’(P.euramericana cv.‘74/76’)、白蜡(Fraxinus chinensis)、法桐(Platanus orientalis)、洋槐(Robinia pseudoacacia)、国槐(Sophora japonica)的气孔密度、开度和大小的影响。结果表明,随着O_3浓度的升高,气孔密度、开度和大小均显著降低,不同树种的各项气孔特征指标之间均存在显著性差异,O_3处理、树种、采样时期以及O_3和树种之间、采样时期和树种之间存在显著交互作用。6种树种的各项气孔指标与O_3剂量(AOT40,小时O_3浓度大于40nmol/mol的累计值)间具有显著的线性负相关关系(P0.05),即随着O_3浓度的升高而显著降低。为深入研究环境变化背景下城市植物的叶组织结构和功能在适应地表O_3污染方面提供理论证据。
