Early experiments investigating the effects of CO(2) enrichment on plants frequently showed photosynthetic stimulation and reduced stomatal aperture over short time periods. Work on the effects of elevated CO(2) has advanced in two major areas: by the extension of long-term and field experiments, and through investigations on the wide range of negative feedbacks affecting plant responses to CO(2). Downward photosynthetic acclimation in response to CO(2) enrichment is frequently observed over the short and long term, and indicates the activity of diverse feedback mechanisms. CO(2) is generally viewed as a limiting photosynthetic resource. However, recent work on stomatal development has shown that this view is simplistic: long- and short-distance signalling of CO(2) concentration are necessary components of normal plant development.
早期研究二氧化碳浓度升高对植物影响的实验经常表明，在短时间内光合作用会受到刺激，气孔孔径会减小。关于二氧化碳浓度升高影响的研究在两个主要领域取得了进展：通过长期和田间实验的扩展，以及通过对影响植物对二氧化碳反应的广泛负反馈的研究。在短期和长期内，经常观察到植物对二氧化碳浓度升高的光合作用向下适应性变化，这表明存在多种反馈机制。二氧化碳通常被视为一种限制光合作用的资源。然而，最近关于气孔发育的研究表明，这种观点过于简单：二氧化碳浓度的长距离和短距离信号传导是正常植物发育的必要组成部分。
