Uptake of Phosphorus-32 by the Roots of Lolium perenne

Abstract

PREVIOUS work on the ability of various portions of the root to supply the shoot with minerals has been carried out using the seminal roots of cereals grown in nutrient solution when the plants were a few days old. Weibe and Kramer1 considered that in barley the most active zone of absorption and translocation of minerals was situated some distance behind the tip. The results of Lundegårdh2, also working on barley, indicated that most nitrate was translocated from the basal portion of the root, that is, that nearest the shoot.
