Weband drought tolerance traits in 26 tree and 19 grass species from the African savanna biome across a gradient of soil water potentials to test for a trade-off between water use under wet conditions and drought tolerance. We measured whole-plant hourly transpiration in a growth chamber and quantified drought tolerance using leaf osmotic ... WebSavanna plants annually experience a long period in which moisture is inadequate for continued growth. Although the aboveground parts of the shallow-rooted grasses quickly dry out and die, the more deeply rooted trees can tap moisture lying further beneath the surface longer into the dry season.
