The Effect of Rubidium-86 Diffusion on the Uptake of Rubidium-86 by Corn¹

ABSTRACT

Uptake of Rb⁸⁶ by corn roots was highly correlated with the diffusion of Rb in soil and kaolinite systems. At values of Dp/b above 1 x 10^-6 cm.² sec.^-1 the relationship was curvilinear whereas it was more nearly linear at rates less than this. The curvilinear relation at the higher rates of diffusion was attributed to the limitations of the rate of absorption of the root.
