Figure 6
Linear regressions showing relationships between essential nutrients, i.e. Cu versus Zn, Mn versus Zn, and Mn versus Cu in the dermal tissue and the vascular bundle of T. latifolia L. The plant samples were collected in 2010 and 2011, respectively. Regression line (I) is for the root dermal tissue, and regression line (II) is for the root vascular bundle. Filled circles: root vascular bundle tissue. Open circles: root dermal tissue. Black lines: linear regression lines. Green dashed lines: 95% confidence level. Red dashed lines: 95% prediction band. |
