Effects of maize seed germination under low-temperature stress on subsequent seedling growth under normal temperature. (A) Phenotypes of seed germination at 13°C for 4 days. (B) Phenotypes of seed germination at 13°C for 7 days. (C) Germination percentage. (D) Phenotypes of seed germination at 25°C for 4 days. (E) Phenotypes of seed germination at 13°C for 4 days followed by 25°C for 2 days. Scale bar, 1 cm. (F) Malondialdehyde (MDA) content. (G) Total antioxidant capacity. (H) Sucrose content. Data are means ± SD (n = 3 replications of thirty plants). Different letters indicate significant differences among means under different treatments ( p < 0.05). FW: fresh weight.
