| 摘 要： | 大气CO2浓度的增加,不仅加剧了全球的温室效应,也改变了全球生态系统中碳的平衡。CO2浓度和温度的升高及交互作用对植物光合作用的影响已经成为目前人们研究的重点。高浓度CO2对植物光合作用的影响表现为短期和长期效应两个方面,短时期的供给高浓度CO2会促进植物的光合作用,而植物对长时间的高浓度CO2处理所作出的响应却表现有所不同,多数植物表现出光合适应现象,而有些木本植物则不表现出这种现象。同样地,温度的升高以及高CO2浓度和高温的交互作用对植物光合作用的影响都存在一定的复杂性。因此,植物光合作用对大气CO2]和温度升高的响应及适应机制的研究亟待深入。 |
| 关 键 词： | 光合作用 响应 适应机制 高[CO2] 高温 |

| Abstract: | The increase of the atmospheric not only aggravates the greenhouse effect of the world,but also changes the carbon balance in the global ecosystem.The effect of elevated atmospheric and temperature and the interaction between them to the photosynthesis has become a research focus.The effect of high on the photosynthesis represents two aspects: short-term effect and long-term effect.Short-term and high can promote the photosynthesis process,however,the plants treated with long-term and high will display the different responses,most of plants show photosynthetic acclimatization,while some of ligneous plants do not exhibit this phenomenon.In the same way,the effect of the elevated temperature and the interaction between the high and high temperature on photosynthetic has a certain complexity.Consequently,further researches are urgently needed on responses and acclimatization mechanism of plant photosynthesis to elevated atmospheric CO_2 concentration and temperature. |
| Keywords: | Photosynthesis Response Acclimatization mechanism High High temperature |
