  1. SW: soil water content; RWC: relative water content of leaves; PRO: proline; SP: soluble protein; SS: soluble sugar. Different capital letters indicate significant differences among different treatments at the same stress time (p < 0.05), different small letters indicate significant differences at different times under the same treatment (p < 0.05), and the same letter or no letter indicates no significant difference between groups (p > 0.05).
