Effect of water stress (WS) on ascorbate (AsA) (a) and glutathione (GSH) (b) contents in Cerasus humilis leaves of Huai’rou (HR) and Nongda4 (ND4). Samples were collected after 21 d of treatment. The data are the mean of at least three replicates with standard errors shown by vertical bars. Asterisk () indicates significant difference with control groups (well-watered) at the 0.05 level of probability by Duncan’s Multiple-Range Test.
