Exogenous Z-3-HAC application conferred salinity stress resistance of peanut seedlings. (A) Shoot dry weight, (B) shoot fresh weight, and (C) growth of peanut seedlings under salinity stress with or without Z-3-HAC priming. The seedlings were primed with distilled water or 200 μM Z-3-HAC twice. After priming, the seedlings were exposed to NaCl stress. At 7 days after the onset of salinity stress treatment, the shoot dry weight and fresh weight were determined, and pictures were taken. Bars are the standard deviations (SD) of three independent replicates (n = 3). Error bars labels with different letters indicate significant differences at p < 0.05 between treatments according to Duncan’s test.
