To assess the phytotoxicity of cadmium (Cd), chromium (Cr), copper (Cu), Nickel (Ni) and zinc (Zn) on seed germination and seedling growth of Hyssop (Hyssopus officinalis L.), experiments were performed in different aqueous concentrations (50, 100 and 150μM) of aforementioned heavy metals over the period of 14 sequential days. The results showed that heavy metals adversely affect the normal gro...

Arable soils are frequently subjected to contamination with copper as the consequence of imbalanced fertilization with manure and organic fertilizers and/or extensive use of copper-containing fungicides. In the present study, the exposure of stone-head cabbage (Brassica oleracea var. capitata) to elevated Cu(2+) levels resulted in leaf chlorosis and lesser biomass yield at ≥2 µ M. Root nitrate ...

The effect of Bradyrhizobium-legume symbiosis on plant growth, toxicological variables and Cu bioaccumulation was studied in white lupin and soybean plants treated with 1.6, 48, 96 and 192 μM Cu. In both species, those plants grown in the presence of root nodule-forming symbiotic Bradyrhizobium showed less root and shoot growth reduction, plus greater translocation of Cu to the shoot, than thos...

copper is an essential micronutrient for plant growth which is involved in many metabolic processes. however excessive amounts of copper may cause environmental pollution. with an increase in the contamination of urban areas with heavy metals, more attention should be paid to the role of ornamental plants in removing pollutants from the soils. the effects of heavy metals on the growth parameter...

to evaluate the impact of the application of thehran municipal solid waste compost (mswc) on zinc and copper concentrations in the soil under maize (zea mays. l.) cultivation, a factorial experiment in base randomized complete block design (rcbd) with two different amounts of municipal solid waste compost (zero, 30.15 and 60 t ha-1) and time (compost applied once or twice) was performed with th...

due to the use of secale montanum for different rangelands reclamation across the country, management of these ecosystems need to be aware of its ability to environmental stresses. this research investigated the effect of pollutant element of cu and pb on seed germination and growth of this species in laboratory. therefore, the effect of five treatments (control, 50, 100, 150, 200ppm) of pb (no...

zinc (zn) and copper (cu) are essential elements and increased plant growth in low concentrations. while high concentrations of these elements as a limiting factor, can cause adverse symptoms on the plants. in the present study, the uptake of micronutrient and macronutrient by pennyroyal were studied in a zn and cu deficiency and toxicity in soil. three levels of copper (0, 5 and 25 mg/kg) and ...
