Influence of root structure on uptake and transport of radioactive phosphorus

A simple device to observe the role of individual root zones in the uptake and transport of nutrients is described. The results confirmed the specific significance of the different anatomical structure of primary seminal maize root in ensuring the uptake and transport of phosphates. In³²p-uptake, the highest portion />40%/was taken up by zone in distance of 0–5 mm from root cap. On the other hand, the lowest transport was shown in the zone 25–30 mm from root tip. The portion of this zone was 40% from the total received supply.
