This study investigated the effect of salinity (control, 8 and 24 ds/m) and light intensity (complete light equal to 1109 × 102 Lux, intermediate light equal to 454 × 102 Lux and weak light equal to 175 × 102 Lux) on some physiological characteristics and ion uptake in Haloxylon ammodendron . The experiment conducted in completely randomizes design in split plot form with 10 replicates. Results...
