Inhibition of Ca2+ and Zn2+ Uptake by Mn2+ in Excised Rice Roots

The effects of varying concentrations of Mn2+ on the absorption of divalent cations, viz., Ca2+ and Zn2+ from 2 concentrations were studied. Mn2+ at all concentrations tested were inhibitory to Ca2+ uptake from 0.1 and 5 mᴍ CaCl2 . However, when Ca2+ uptake was measured at concentrations ranging from 0.05 to 10 mᴍ CaCl2, MnCl2 only at high concentration of 5 mᴍ, inhibited Ca absorption. Zn2+ uptake from 0.1 mᴍ ZnCl2 was decreased by all concentrations of Mn2+.
