Abstract
To our knowledge there has been no research on Artemisia aucheri as a halophyte plant, when grown in cadmium (Cd) contaminated soils. We tried to quantify the ability of A. aucheri in uptake of Cd and some nutrients in contaminated soil. In a pot culture experiment, five levels of Cd concentration were tested by adding 15, 30, 60, 120 and 240 mg of Cd per kilogram of dried soil. Plants were harvested and analyzed for Cd, N, P, K, Mg, Mn, Cu, Fe and Zn uptake. Depression in biomass production of plants as a result of excess Cd was observed. Cadmium concentration in plant shoots plant increased with increasing Cd supply significantly affecting the content of plant nutrients. Cd excess amounts increased macronutrients and decreased micronutrients concentrations in plant.
Highlights
Heavy metal contamination of soil and groundwater causes major environmental and human health problems
The aim of our research was to investigate the effects of excess cadmium on biomass production, Cd concentration, and uptake and translocation of some nutrients including nitrogen (N), phosphorus (P), potassium (K), magnesium (Mg), iron (Fe), manganese (Mn), copper (Cu) and zinc (Zn) in A. littoralis
Cadmium concentrations in roots significantly increased with Cd levels increasing from 15 to 60 mg kg-1, and significantly decreased as Cd concentrations increased from 60 to 240 mg kg-1
Summary
Heavy metal contamination of soil and groundwater causes major environmental and human health problems. Investigating the survival of salt-tolerant halophytes under heavy metal stress seems pertinent (Shevyakova et al, 2003)
