Fig. 2.

Dynamics of ⁶⁵Zn and ¹⁰⁹Cd in wheat plants. The plants were dissected into the labelled part of the main root, the lateral roots branching from the labelled part of the main root, the apical part of the main root, the other roots, the grain, the scutellum (including the scutellum, the small shoot axis and the shoot apex), the coleoptile and leaf 1 (oldest leaf) to leaf 8 (youngest leaf). Means and standard errors of four replicates are shown for the radionuclide contents (cpm) in the different plant parts.
