WebbVarious definitions of water-use efficiency. In general, water-use efficiency is defined as the ratio of carbon assimilation to water consumption. But according to different research scale and purpose, it can be calculated in different ways. At the leaf scale, the Intrinsic Water-use Efficiency is defined as the amount of carbon assimilated per ... WebbPatterns of photosynthesis, inherent water-use efficiency (IWUE) and tree transpiration indicate that the young plantation responds to the seasonal drought sooner and to a more severe degree. Lower sensitivity to seasonal drought at the mature site is likely due to higher soil moisture reserves year round and a deeper root system that can access …
Webb1 mars 2024 · Water use efficiency (WUE), the ratio of carbon uptake to water use, has been commonly used as a proxy to study the relationship between forest carbon and water in forest ecosystems. WUE is used to evaluate the potential impacts of climate change on food production [ 10, 11 ], water supply [ 7 ], and forest or land use management [ 12, … Webb10 juni 2024 · Water use efficiency (WUE) is a measure of the trade-off between carbon gain and water loss in plants or terrestrial ecosystems (Liu et al. 2015 ), both of which …
