Table 3 Growth indices of the cucumber seedlings subjected to different ALA concentrations under medium NaCl stress

From: Heme is involved in the exogenous ALA-promoted growth and antioxidant defense system of cucumber seedlings under salt stress

ALA concentration (mg L–1) Plant height (cm) Stem diameter (mm) Fresh weight (g plant–1) Dry weight (g plant–1)
0 6.98 ± 0.08 c 4.62 ± 0.07 c 9.17 ± 0.04 c 0.52 ± 0.01 b
10 8.75 ± 0.15 b 5.01 ± 0.7 ab 10.09 ± 0.08 b 0.55 ± 0.02 ab
25 10.39 ± 0.23 a 5.21 ± 0.05 a 12.12 ± 0.07 a 0.65 ± 0.01 a
