植物消耗每单位水产生的生物量被称为全株水分利用率(WUEplant,whole plant water use efficiency),主要受光合作用和蒸腾作用影响;植物的二氧化碳同化与气孔导度的比率被称为先天水分利用率(iWUE,intrinsic WUE);WUEplant直接受iWUE影响,因此气孔导度变化对WUEplant影响较大【2】。植物激素ABA是调控气孔开关的关键因子,...

Central Role of Water-Use Efficiency Behind the evolution ofdryland farmingin the semi-arid Great Plains is the story of water-use efficiency and the factors that influence it. Water-use efficiency is the ratio of crop plant matter produced per inch of water used by the crop. It is influenc...
Leaf and Plant Water Use Efficiency in Cocksfoot and Tall Fescue Accessions under Differing Soil Water Availability Water availability is one of the most important limiting factors in plant production worldwide. Such limitation is expected to increase in regions with a M... Gulias,Seddaiu,Cifre,....
the water use efficiency of different kinds of plants,the relationship of water use efficiency to drought tolerance,the genetic background of water use efficiency, the methods to improve water use efficiency on various scales and the trends of research on water use efficiency in the near future....
"Water Use Efficiency in Plant Biology" is the first book to provide comprehensive coverage of water use efficiency at the molecular, cellular, whole plant, and community levels to present the treatment with a biological focus. This area of biology is of direct relevance to agricultural economics...
Qustion 10 :How Does the Continuing Rise in CO2 Affect the Regulation of Stomatal Apertures and Water Use Efficiency of Plants? Qustion 11 :How can one aquaporin have so many roles in a plant? Qustion12 :How can one aquaporin have so many roles in a plant?
This paper described the application of stable hydrogen,carbon and oxygen isotopes techniques in tracing sources of plant water and water use efficiency. Since the process that plant roots uptake water is non-fractionating,plant xylem water has the same composition of stable hydrogen and oxygen isotop...
To investigate the comparative tolerance ability of wheat, barley, canola and chickpea to subsoil NaCl salinity and its impact on water uptake, water use efficiency, plant growth and ionic balance, a pot experiment was conducted on a heavy texture soil (sodic vertosol) having 20 ESP (...
