Phytoextraction du cuivre par l’Atriplex canescens L. dans un milieu salin, étude des paramètres biométriques, hydriques et minéraux de la plante.

Abstract

The present study was conducted to test the plant's ability to reform and saline soils contaminated with heavy metals through absorption and accumulation in root and leaf, we used in this research adaptable plant with the salinity of the plant (Atriplex canescens) It has been watering this plant for a month by solvents sodium chloride two deferent concentration (5 and 30g /l) and the copper sulfate increasing concentrations (2000, 2500.3000 ppm), in addition to the combined effect of these two elements. At the end of the experiment, we calculated biometric of (leaf area, length of the rods and root volume) and water standards (the amount of water, the water content was measured and the ratio of evaporation) and the metal of (sodium, potassium). Show us through the results obtained by the emergence of highly resistant to leaf (cut) up to the extent of concentration of 3000 ppm of copper sulfate dissolved with concentration of 30 grams per liter and through the increase in the length of her legs and the evolution length of the rods and root volume. sodium ions more potassium ions on the leaves and roots level, this accumulation varied from concentration to another, both when he was watering with saline only or metallic or taking part together.
