Effect of atmospheric concentration of water vapour and CO2 in determining transpiration-photosynthesis relationships of cotton leaves

Assessment of wheat and maize water productivities and production function for cropping system decisions in arid and semiarid regions

“…It requires a shift in irrigation science, irrigation water management and basin water allocation to move away from ''maximum irrigation-maximum yield'' strategies to ''less irrigation-maximum crop WP'' policies (Oweis and Hachum, 2006). The influences of climatic parameters on the relation between photosynthesis and transpiration have been described in many studies (De Wit, 1958;Bierhuizen and Slayter, 1965;Tanner and Sinclair, 1983). Tanner and Sinclair (1983) found a proportionally inverse relationship between vapor pressure deficits of the air and crop WP.…”

Osmogenetics: Aristotle to Arabidopsis

“…The ratio of dry weight (mainly from CO 2 ) gained (growth) to water lost is called water use efficiency (WUE) and is a fundamental factor controlling the maximum size (growth) of plants that are exposed to environments with limited water availabilities. WUE was first described by Bierhuizen and Slatyer (1965) and varies considerably between species as clearly demonstrated first in the data of Briggs and Shantz (1914) and later by many others (de Wit, 1958;Passioura, 1977;Farquhar and Sharkey, 1982). Genetic control of optimizing the amount of CO 2 gained per amount of water lost is dramatically illustrated by the description of C4 photosynthesis in 1966 by Hatch and Slack (see Salisbury and Ross, 1992) and in the extreme example of C4 crassulacean acid metabolism plants that have a WUE 3 to 5 times greater than other plants.…”

Physiological and growth responses of Populus davidiana ecotypes to different soil water contents

“…For long time there has been a considerable effort to elucidate the degree and nature of the genetic control over water use efficiency (WUE) in plants, WUE is traditionally defined either as the ratio of dry accumulation to water consumption over a season (WUE T ) or as the ratio of net photosynthesis (A) to transpiration (E) over a period of seconds or minutes (WUE i ) (Bierhuizen and Slatyer, 1965;Sinclair et al, 1984). In recent years much attention has been devoted to the study of carbon isotope composition (d 13 C) of plant tissues (Farquhar and Richards, 1984;Martin and Thorstenson, 1988;Osorio and Pereira, 1994;Leroux et al, 1996;Li et al, 2000;Amdt et al, 2001) and d 13 C has been developed as a tool to measure WUE, because a strong correlation is found between d 13 C and WUE (Farquhar et al, 1989).…”
