Dimensions of root cells in each cell layer

Cell layers are numbered from the epidermis (1) toward the root axis. Values are means ± se (n = 22–59) from 10 roots. The data were combined for cell layers 4 to 6 of yellow lupin and cell layers 2 to 4 of wheat because no significant differences could be found between these cell layers. Volumes were only determined for those cell layers punctured by the cell pressure probe.
