Effect of Chloride on Phosphorus Uptake by Corn Roots1
- O. G. Carter and

A study was made on the effect of KCl on P uptake by 20-day-old corn seedlings grown in water culture and 4-day-old excised corn roots grown on 0.2 mM CaSO4 solution. All P solutions were adjusted to pH 4. Those used for excised roots contained 0.2 mM CaSO4 and those used for 20-day-old corn seedlings contained 1.2 mM KNO3, 0.8 mM Ca(NO3)2, and 0.4 mM MgSO4. One-hour absorption periods using concentrations up to 0.l M KCl showed no effect on 32 uptake from 2 to 260 µM KH2PO4 solutions with either type of plant material.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
