Abstract: Water deficits cause large yield losses in wheat. Although anthesis is generally considered the most vulnerable period, water deficit during grain filling can also cause yield losses. The objective of this study was to investigate the effect of water stress and rewatering, at three different grain developmental stages, on physiological and grain filling parameters and on yield components. Wheat plants were subjected to water deficit and rewatering at the watery ripe, milk and soft dough stages. In the flag lea… Show more

“…It is well known that many biotic and abiotic factors can affect the grain-filling rate of wheat crop (Calderini et al 2001). It has also been noticed that abiotic stresses occurring at different stages after anthesis could affect grain-filling rate differently (Beltrano et al 2006).…”

“…Wheat (Triticum aestivum L.) is an important crop in the Argentinean southeastern Pampa, where high temperatures and water stress often reduce plant growth and crop yields (Beltrano et al, 2006). Drought is a complex phenomenon, and is considered one of the most important factors limiting crop yields around the world.…”

“…Cellular membrane stability, measured as the conductivity of electrolytes leaking from leaf disks at high temperature, has been suggested as a screening technique to determine heat tolerance in plants (Sullivan, 1972). Several studies have suggested the effectiveness of this technique in detecting genetic variability in heat tolerance in crops such as soybean (Martineau et al, 1979), sorghum (Sullivan, 1972), wheat (Saadalla et al, 1990), Kentucky bluegrass, salt-stressed maize (Feng et al, 2002), and drought-stressed wheat (Beltrano et al, 2006).…”

“…Bajo estas condiciones, la acumulación de almidón es más sensible que la acumulación de proteínas. Un incremento en la concentración de proteínas en el grano puede ocurrir sin un aumento en el contenido de prote ínas per se (Beltrano et al, 2006). Quiriban et al (2015) encontraron que al disminuir la dis ponibilidad de agua, en inicio de encañazón, se redujo el 51% el peso del grano y aumentó el 43%, la concentración de proteínas del grano en ACA 315, mientras que en Baguette P. 11, el peso del grano se redujo el 37% y el aumento del % de proteínas fue del 17%.…”
