Effects of climate change on water use efficiency in rain-fed plants
Water use efficiency (WUE) reflects the coupling of the carbon and water cycles and is an effective integral trait for assessing the responses of vegetated ecosystems to climate change. In this study, field experiments were performed to examine leaf WUE (WUEleaf) in response to changes in CO2 concentration and other environmental variables, including soil moisture and air temperature. We al...
متن کاملNutrient Use Efficiency in Plants
Invariably, many agricultural soils of the world are deficient in one or more of the essential nutrients needed to support healthy plants. Acidity, alkalinity, salinity, anthropogenic processes, nature of farming, and erosion can lead to soil degradation. Additions of fertilizers and/or amendments are essential for a proper nutrient supply and maximum yields. Estimates of overall efficiency of ...
متن کاملWater-use efficiency and relative growth rate mediate competitive interactions in Sonoran Desert winter annual plants.
UNLABELLED PREMISE OF THE STUDY A functional approach to investigating competitive interactions can provide a mechanistic understanding of processes driving population dynamics, community assembly, and the maintenance of biodiversity. In Sonoran Desert annual plants, a trade-off between relative growth rate (RGR) and water-use efficiency (WUE) contributes to species differences in population...
متن کاملWater use efficiency of controlled alternate irrigation on root-divided maize plants
A new method of irrigation was designed and tested for its water use efficiency (WUE). Maize plants were grown in pots with their roots divided and established into two or three separated containers of which irrigation and soil drying were controlled alternately. Results showed that when the two halves of the root system were alternatively exposed to a drying soil and a soil with its water cont...
متن کاملVirtual water trade: an assessment of water use efficiency in the international food trade
Amid an increasing water scarcity in many parts of the world, virtual water trade as both a policy instrument and practical means to balance the local, national and global water budget has received much attention in recent years. Building upon the knowledge of virtual water accounting in the literature, this study assesses the efficiency of water use embodied in the international food trade fro...
