Effect of chilling/cold stress on RGR, Fv/Fm, H₂O₂ generation and DPPH scavenging capacity in mungbean. Leaves of 4-DAI seedling were used to measure RGR (a), Fv/Fm (b) and whole seedlings of 3-DAI were used for in situ H₂O₂ detection (c) and measurement of DPPH scavenging capacity (d). Treatment time in a is indicated by a dash line with starting (downward) and ending (upward) arrows. Data were analyzed with two-way ANOVA and Student–Newman–Keuls test. Symbols indicate significant difference between NM94 and VC1973A; *P < 0.05, **P < 0.01, ***P < 0.001
