  1. The experiments consisted of four treatments: NT: normal temperature; NT+GSH: normal temperature plus exogenous GSH treatment; HT: high root-zone temperature treatment; and HT+GSH: high root-zone temperature plus exogenous GSH treatment. Data represent the mean ± SD (n = 3). Different letters indicate significant differences at P < 0.05 based on the Least Significant Difference test.
