Upper and lower triangles indicate correlation coefficients under salt stress and control conditions, respectively. Diagonal values indicate correlation coefficients between control and salt stress conditions. All correlation coefficients are significant at p < 0.01 except for values in italics; values in bold indicate strong correlation (r > 0.8). GI, germination index; VI, vigor index; MGT, Mean germination time; IR, imbibition rate; GR, germination rate
