  1. Correlation coefficients were analyzed among root traits detected on the same day, and values greater than 0.90 are highlighted in italics. The symbol * or ** indicates that the correlation between root traits is statistically significant at the level of 0.05 (P < 0.05) or 0.01 (P < 0.01), respectively
