Figure 5
Linear regressions showing relationships between essential nutrients, i.e. Cu versus Zn, Mn versus Zn, and Mn versus Cu, in the dermal tissue with Fe plaque and the regular dermal tissue. The T. latifolia L. samples were collected in 2010 and 2011, respectively. Regression line (I) is for the dermal root tissue with Fe plaque, and regression line (II) is for the regular root dermal tissue. Filled circles: regular root dermal tissue. Open circles: root dermal tissue with Fe plaque. Black lines: linear regression lines. Green dashed lines: 95% confidence level. Red dashed lines: 95% prediction band. |
