Carbon uptake and water use by plants: is there pre-stomatal control?

社会依赖于对气候变化、天气预报、作物表现和其他过程的数学描述，在这些过程中，控制植物的碳吸收和水分损失构成了一个基本要素。科学家还使用相同的元素来确定二氧化碳(CO2)的来源和汇，描述植被、水文和生态过程。这一元素的一个关键生理学假设现在存在疑问，我们将对其进行严格测试，并在必要时提供一个可靠的替代方案。为了做到这一点，我们将开发一个关于完整树叶功能的新“窗口”，它将揭示树叶内水蒸气和其他气体的浓度。

Society relies on mathematical descriptions of climate change, weather forecasting, crop performance, and other processes in which the control of carbon uptake and water loss by plants forms a basic element. Scientists also use the same element in ascribing sources and sinks of carbon dioxide (CO2), describing vegetation, hydrological and ecological processes. A key physiological assumption in this element is now in doubt and we will test it rigorously and if necessary provide a robust alternative. We will do this by developing a novel 'window' on intact leaf functioning that will reveal the concentration of water vapour and other gases inside leaves.
