Coordination in functional traits of Populus euphratica leaves under salt stress

Leaf functional traits allow plant survival and maintain their ecosystem function. Salinity affects leaf traits, but coordination among is poorly known may depend on salt severity. To increase our understanding of the under stress, we determined hydraulic, gas exchange, physiological biochemical parameters in Populus euphratica Oliv. ( P. ) grown salinity treatments, as well exchange different CO 2 concentrations. We found that can reinforce its hydraulic capacity by increasing water transfer efficiency both leaves stems when a threat occurs for specific duration stress. Its were more adaptable than leaves. The economic consistent during middle stages inconsistent onset late There was almost no limitation severe conditions, enrichment had greater effect traits. mechanism toxic ion exclusion based availability intracellular mechanisms contributed to tolerance exposed also plants coordinate with form defense reduce damage guarantee growth saline conditions. In conclusion, , main constructional species riparian forests, adapts environments adjustment ensuring survival. These results provide scientific basis forest restoration.
