Última Water relations and hydraulic architecture in Cerrado trees: adjustments to seasonal changes in water availability and evaporative demand Braz. J. Plant Physiol. Bucci,Sandra J.; Scholz,Fabian G.; Goldstein,Guillermo; Meinzer,Frederick C.; Franco,Augusto C.; Zhang,Yongjiang; Hao,Guang-You. We determined adjustments in physiology and morphology that allow Neotropical savanna trees from central Brazil (Cerrado) to avoid water deficits and to maintain a nearly constant internal water balance despite seasonal changes in precipitation and air saturation deficit (D). Precipitation in the study area is highly seasonal with about five nearly rainless months during which D is two fold higher compared to wet season values. As a consequence of the seasonal fluctuations in rainfall and D, soil water potential changes substantially in the upper 100 cm of soil, but remains nearly constant below 2 m depth. Hydraulic architecture and water relations traits of Cerrado trees adjusted during the dry season to prevent increasing water deficits and insure...
