1) elevated O_3
升高O_3浓度
2) 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。
3) High ozone concentration day
高浓度O_3日
4) 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。
5) Second peak of ozone concentration
O_3浓度次峰
6) elevated atmospheric CO2 concentration
CO2浓度升高
1.
This paper reviews the current researches about the effects of elevated atmospheric CO2 concentration on photosynthesis, including photosynthetic pigment content varies differently in different plants and photosynthetic rate increa.
大气CO2浓度升高对植物光合作用的影响主要体现在:对不同植物的光合色素含量均有影响,但结果有所差异;短期处理光合速率提高,而长期处理则可能出现光合适应,其适应机理目前尚存在分歧;不同光合类型植物的叶片形态结构有不同的响应结果,叶绿体超微结构也明显变化;生物量和产量提高。
