Differential water-use strategies and drought resistance in Trichloris crinita plants from contrasting aridity origins

In arid environments, water availability is the main limiting factor for primary production, and it is expected that not only drought-resistance, but also plant strategies for soil water use will be under natural selection. Our aim was to investigate the strategies of soil water use and the response...

Our aim was to investigate the strategies of soil water use and the responses to water shortage that lead to variability in drought resistance in Trichloris crinita plants (a native forage grass of northwestern Argentina) from sites with contrasting aridity. We established a common-garden experiment with plants from relatively “arid” and “humid” sites (326 and 625 mm mean annual precipitation, respectively). During 6 weeks, plants were subjected to two contrasting watering levels: control and drought. We found different water use strategies and drought resistance between plants from arid and humid sites: the former used water more conservatively and grew more under drought. During the first 2 weeks of the drought treatment, plants from arid sites dried out the soil slower than those from humid sites. Plants from arid sites subjected to drought showed less leaf senescence and a greater leaf elongation rate and biomass of green leaves than those from humid sites. This variability in adaptation to drought in T. crinita plants could be used to select plant materials for arid land revegetation or to be incorporated into breeding programs for forage purposes.Fil: Quiroga, R.
