In order to study of the effect of priming and salinity on physiological and chemical characteristics of wheat(Triticum aestivum L.), an experiment was carried out at the Experimental Farm of Shiraz University. Results showedthat primed plants significantly reduced its gas exchanges by accelerating senescence under a series of salt stress,which became more serious along with the increasing of s...

Introduction: A major concern of human being is accumulation and toxicity of heavy metals in their body. Copper is a heavy metal ion that in concentration of 2 mg/l can cause numerous complications. Different treatment methods have been proposed for removing metals from contaminated water by researchers. Among these methods, sorption seems a better method with high removal efficiency. In this s...

Calcium and strontium ions enhanced rishitin but not lubimin accumulation in tuber tissue of potato (Solanum tuberosum cv Kennebec) treated with arachidonic acid (AA). The same cations in the presence of poly-l-lysine (PL) enhanced the accumulation of lubimin more than rishitin. In contrast, Mg(2+) did not affect AA-elicited rishitin and lubimin accumulation and inhibited the accumulation of th...

this study was designed to investigate the effect of p. fluorescens fy32 inoculation on the activities of some antioxidant enzymes and ion concentration of two canola cultivars (sarigol and hyola308) under salinity stress (150 and 300 mm nacl) in the greenhouse condition (fall 2012, dept. of plant breeding and biotechnology, faculty of agriculture, university of tabriz). the experimental design...

A sodium dodecyl sulfate modified carbon paste electrode (SDS/CPE) was developed in this work based on the surface modification method. The modified electrode was prepared by immersing SDS/CPE in a nickel nitrate solution. This electrode showed a strong accumulation ability toward nickel ions. Then modified electrode was conditioned by potential recycling in a potential range of 0.2–0.8 V (vs. ...

A newly developed Smart Pouch with enclosed biomaterial (Aloe vera and coconut husk powder) has been experimented for elimination of heavy metals i.e. (Pb2+, Cu2+, Ni2+ and Zn2+) from wastewater. The effect of concentration, pH, temperature, contact duration etc. was investigated using batch experiments which resulted that the Pouch may be accepted for convenient, efficient and low-cost accumul...

Environmental remediation of hazardous metals like Cd(II), and Co(II) ions is very necessary due to their toxicity at trace accumulation levels in the biosystem. In this study, sorption Co(II), Cd(II) from aqueous solutions onto titano-silicate (TiSi) ion exchange material in-situ dopping composites cobalt (Co-TiSi) cadmium (Cd-TiSi) was achieved. TiSi were obtained by precipitation technique c...

Effect of salinity on sprouting water uptake, ion uptake and metabolic efficiency of wheat seeds in the variety kanchan were studied in Jaydebpur. The treatments were 0, 4, 8, 12 and 16dS salinity level. The experiment was set in CRD with four replications. There were 50 seeds per petridish. Seeds were moistened with saline solution. Germination was recorded up to 72 hours with an interval of 1...

The relationship between ammonium accumulation and senescence of detached rice leaves caused by excess cadmium (Cd) was investigated. CdCl(2) was effective in increasing ammonium content in detached rice leaves under both light and dark conditions. Both CdCl(2) and CdSO(4) induced ammonium accumulation in detached rice leaves, indicating that ammonium accumulation is induced by Cd ions. CdCl(2)...
