Abstract
The accumulation of sodium (1 mN NaCl) was measured in different root tissues, the cell wall, the cortex and the stele. The effect that calcium could have on this process in the separated parts of the root was also investigated, since it is known [1] calcium effects the sodium uptake at different levels. It is only in recent years that some workers have been trying to find out what relative importance each different part of the root could have in the whole process of accumulation and transport of ions through the root system [2, 3]. The difference between cortex and stele was already stated [4, 5]. Cell walls were prepared from whole roots by a Triton X-100 detergent treatment [6]. The separation of the other parts was obtained by stripping the roots.
