Correlation analysis of different evaluated traits in Soybean. Traits for correlation analysis: qL ratio = qL_Cold/qL_CK, Fv/Fm ratio = Fv/Fm_Cold/Fv/Fm _CK, Leaf injury ration (LI) ratio = LI_Cold/LI _CK, Non-photochemical quenching (NPQt) ratio = NPQt_Cold/NPQt_CK, phiNO ratio = phiNO_Cold/phiNO _CK, Leaf thickness (LT) ratio= LT_Cold/LT_CK, and SPAD ratio= SPAD _Cold/SPAD _CK. The ***, ** and * asterisks indicate the significant correlation at p-value <0.001, <0.01 and p-value <0.05, respectively.
