Combined Salinity and Lead on Physiological Responses of Atriplex Action; A. halimus L., A. canescens (Pursh) Nutt

These plants were submitted under the combined action of salinity-lead on the physiological responses of these two species Atriplex halimus L. and Atriplex canescens (Pursh) Nutt.. These plants have made ​​an abiotic stress for a week sprinkled with solutions containing different concentrations of lead, 1000 ppm, 3000 ppm, 5000 ppm pb(NO 3 ) 2 in the presence of NaCl salt at two different concentrations, 300 and 600 meq.l -1 compared with the results from control plants that are watered by nutrient solution HOAGLAND. Both species have undergone the same treatment. The study was based on: the determination of the content of minerals such as potassium, sodium and calcium on the aerial part (leaves), and the root portion.
