The variation in flavonoid compositions of ZBLs under drought stress. (A): the phenotype of ZBLs under drought stress. F1–F4 indicate FJ leaves exposed to drought treatment for 0 d, 6 d, 9 d, and 12 d; H1–H4 indicate HJ leaves exposed to drought treatment for 0 d, 6 d, 9 d, and 12 d. (B): the relative content of total flavonoid of ZBLs from FJ and HJ under drought stress. D1–D4 indicate the four drought treatment stages. (C): Classifications and proportions of 231 flavonoids detected in ZBLs. The mean values and SDs were calculated using one-way ANOVA followed by Duncan's multiple range test.
