Table 1 Pearson’s phenotypic correlations among the root system architecture and related traits in the hydroponic experiment. The top and lower diagonals of the top portion represent the correlation coefficients among the target traits in control and drought stress, respectively. The top and lower diagonals of the lower portion of the table represent the correlation coefficients among the target traits under low-nitrogen and salinity stress, respectively.
