Plant Respiration in Elevated CO2: Mechanisms of Response

格里芬 9603940 植物的光合作用和呼吸作用是两个生物过程，它们将CO转移到植物体内或从植物体内转移出来。 年净收入），并大大高于年净收入。 大气中的增量， 人类活动，如化石燃料挖掘和森林砍伐 （约32亿吨/年） 年，合并）。大气中二氧化碳的变化可以 反馈并改变 植物与大气交换碳。因此，速率和/或 未来变化的程度 温室气体排放受到这个反馈回路的影响 植物和大气之间的关系。 对植物呼吸的长期影响，它仍然是根本 不清楚为什么会这样。因此，目标 影响植物的呼吸速率，从而提供了一个更好的 预测二氧化碳如何 21~世纪的地球大气

Griffin 9603940 Photosynthesis and respiration by plants are two biological processes that transfer CO into and out of year, respectively), and substantially greater than the annual net increment to the atmosphere from human activities such as fossil fuel burrung and deforestation (approximately 3.2 billion metric tons per year, combined). The resulting changes in atmospheric CO2 can feedback and change the rate at which plants exchange carbon with the atmosphere. As such, the rate and/or extent of future changes in greenhouse gas emissions are influenced by this feedback loop between plants and the atmosphere. long-term effects on plant respiration, it is still fundamentally unclear why it does. Accordingly the goal effects the rate of plant respiration, thereby providing a more substantial capacity to predict how CO earth~s atmosphere in the 21~ century.
