  1. ACC indicates 1-Aminocyclopropanecarboxylic acid, TZ indicates trans-Zeatin, IPA indicates N6-isopentenyladenosine, IAA indicated Indole-3-acetic acid, ABA indicates ( +)-Abscisic acid. Q0 treatment of water, Q1 treatment with ABA, Q2 treatment with NaCl, Q3 treatment with ABA + NaCl in Chaoyouqianhao. Z0 treatment of water, Z1 treatment with ABA, Z2 treatment with NaCl, Z3 treatment with ABA + NaCl in Huanghuazhan. Values are mean ± standard error of three replicates (n = 3). Within each column, different letters indicate significant difference at the five percent significant level according to Duncan's multiple range tests.
