Fig. 2From: Gamma-aminobutyric acid (GABA) alleviates salt damage in tomato by modulating Na+ uptake, the GAD gene, amino acid synthesis and reactive oxygen species metabolismSalt injury index and plant height growth rate of tomato seedlings under NaCl stress with or without GABA. a: salt injury index, b: plant height growth rate. Note: Each value is the mean ± SD of three independent experiments. Different lower-case letters in each column shape indicate significant difference at P < 0.05 by Duncan’s testBack to article page
