Growth, physiological characteristics, and their relationships of mesocotyls in two contrasting maize genotyes (N192 and Ji853) under 3 cm sowing depth (CK), 20 cm sowing depth (DSS), 4.16 × 10−3 M 24-epibrassinolide (EBR) induction at 20 cm sowing depth (DSS + EBR), 4.16 × 10−3 M EBR and 3.05 × 10−3 μM brassinazole (BRZ) induction at 20 cm sowing depth (DSS + EBR + BRZ). EBR and BRZ structures (A). Mesocotyls observation in N192 and Ji853 under four conditions (B). Statistics of mesocotyl length (MESL), mesocotyl weight (MESW), malondialdehyde (MDA) content, H2O2 content, lignin content, SOD activity, CAT activity, and POD activity of mesocotyls in N192 and Ji853 under these conditions. Different lowercase letters with a single maize genotype among four conditions represented significant differences with p < 0.05 level (C). Interactive ring correlation plot of these traits in both maize genotypes under three conditions (CK, DSS, and DSS + EBR) was performed by a free online Genescloud tool (https://www.genescloud.cn; accessed on 10 December 2021). The connection curve in both traits showed a significant positive or negative correlation in p < 0.05 level (D).
