Data sets

ata of environmental factors and sap-flow rate in 2013 and 2014 and data of stomatal conductance (gs) in 2013 and 2014 Beijing Forestry University https://pan.baidu.com/s/1sl8wgVz

Short summary

According to this study, Artemisia ordosica escaped water limitations by invoking a water-conservation strategy with the regulation of stomatal conductance and advancement of sap-flow peaking time, manifesting in a hysteresis effect. This study provides a significant contribution to the understanding of acclimation processes in desert-shrub species to drought-associated stress in dryland ecosystems.
