Última Water stress and forage production in Tetrachne dregei Nees, Panicum coloratum L. and Eragrostis curvula (Schrad) Nees Phyton Ruiz,MA; Golberg,AD; Martínez,O. Tetrachne dregei, Panicum coloratum and Eragrostis curvula are perennial forage C4 grasses, introduced from South Africa to the pampean semiarid region. This work was carried out to compare water stress tolerance; forage production and quality of T. dregei, P. coloratum and E. curvula. Studies were conducted under greenhouse and field conditions. In the greenhouse, watering was stopped after eighty one days of plant emergency in the water stress treatment. Water potential (ψ), stomatal resistance (SR) and shoot and root weights were evaluated. Under water stress, ψ diminished earlier and SR increases were higher in P. coloratum than in T. dregei and E. curvula. Plant survival in T. dregei and E. curvula was higher than that of P....

In semiarid regions rainfall is often scarce and erratic in space and time, making valuable the exploration of news genotypes with superior behavior in dry land systems. Tricepiro (X Triticosecale Wittmack x X Agrotriticum Ciferri & Giacom) is a synthetic cereal with long cycle and high biomass production in semiarid environments. However its performance under controlled water stress has not yet been evaluated. The aim of this work was to investigate the effect of water stress on tricepiro genotypes in comparison with their progenitors: triticale and trigopiro. Morphophysiological traits related to forage yield were evaluated in the greenhouse and the field. In the greenhouse, water potential, stomatal resistance, root biomass and wilted/green...
