虽然短期暴露在大气CO2浓度升高会导致许多植物光合作用的大幅增加，但由于光合作用能力的降低，长期暴露在二氧化碳浓度升高的环境中往往会导致较小的光合作用增加。在这项研究中，研究表明，对于生长在自然环境中的野生C3物种来说，在四个生长季节暴露在高二氧化碳中，其光合作用能力实际上增加了31%。在田间生长的其他物种中也观察到了光合作用能力的增加，这表明某些田间种植的植物的光合作用将继续对大气中二氧化碳水平的升高做出反应。
While a short-term exposure to elevated atmospheric CO2 induces a large increase in photosynthesis in many plants, long-term growth in elevated CO2 often results in a smaller increase due to reduced photosynthetic capacity. In this study, it was shown that, for a wild C3 species growing in its natural environment and exposed to elevated CO2 for four growing seasons, the photosynthetic capacity has actually increased by 31%. An increase in photosynthetic capacity has been observed in other species growing in the field, which suggests that photosynthesis of certain field grown plants will continue to respond to elevated levels of atmospheric CO2.
