1) Second peak of ozone concentration
O_3浓度次峰
2) O3 concentration
O_3浓度
1.
The different O3 concentration experiments on spinach and Chinese cabbage were conducted in open top chambers and the impacts of different O3 concentration on the growth and development,physiological characteristic parameters of spinach and Chinese cabbage were analyzed.
利用OTC-1型开顶式气室对菠菜和青菜进行不同O_3浓度熏气试验结果表明,当大气中O_3浓度升高,菠菜和青菜气孔阻力增大,光合作用速率下降,地上部和地下部生物量大幅度降低,当O_3浓度达200μmol/kmol时,菠菜和青菜地上部生物量分别不足对照的1/9和1/3,地下部生物量分别下降79。
3) High ozone concentration day
高浓度O_3日
4) elevated ozone
O_3浓度升高
1.
trees are exposed in the open-topchambers to two levels of ozone concentration (ambient, approximately 45nmol/mol andelevated ozone, 80±8 nmol·mol~(-1))in order to study the effect of elevated ozone on activeoxygen species, lipid peroxidation and antioxidative systerm in Pinus tabulaeformis Carr.
本文采用开顶箱(Open-top chamber,简称OTC)方法,研究分析O_3浓度升高(80±8nmol/mol)对沈阳市主要绿化树种——银杏与油松叶片膜脂过氧化程度的动态变化、活性氧积累及抗氧化系统的影响,揭示O_3浓度升高条件下银杏与油松活性氧及抗氧化系统的变化机理及响应规律。
5) elevated O_3
升高O_3浓度
6) elevate CO2 and O3 concentrations
CO_2和O_3浓度增加
