Gas change characteristics of five-year-old seedlings and one-year-old resprouts. a Photosynthesis rate (Asat), b stomatal conductance (gs), (c) transpiration rate (E) and (d) water use efficiency (WUE) of one-year-old resprouts and five-year-old seedlings. Darkgreen labeled control represents five-year-old seedlings; tan labeled resprout represents one-year-old resprouts; *** (P < 0.001) indicates significant differences between one-year-old resprouts and five-year-old seedlings; ns indicates non-significant differences detected; AC A. canescens, CK C. korshinskii, CM C. mongolicum, HS H. scoparium; standard error bar was showed above each column (one-way ANOVAs)
