Leaf water potential of one-year-old resprouts and five-year-old seedlings. Predawn and midday leaf water potential 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; △indicates the differences between leaf water potential in midday and predawn; Ψpre represents leaf water potential at predawn; Ψmid represents leaf water potential at midday; *** (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)
