GROWTH AND PHOSPHORUS UPTAKE OF ATRIPLEX-AMNICOLA AT DIFFERENT LEVELSOF NACL

Growth of Atriplex amnicola P.G. Wilson was not affected by different levels (10, 100, and 200 mM) of NaCl. Na concentrations in roots and s hoots increased significantly at higher levels of NaCl. K/Na ratios in plant parts were higher compared to those in the external solutions, indicating selectivity for K over Na. P uptake, as determined using P- 32, was not affected by increasing NaCl in the root medium.
