The influence of selenium supplementation during chelation therapy to reduce body burden and toxicity of lead was investigated in rats. Selenium had marginal effects on liver, kidney and blood lead decorporation by calcium disodium ethylenediamine tetra acetic acid (CaNa2EDTA) and activation of inhibited delta- aminolevulinic acid dehydratase (ALAD) activity by calcium trisodium diethylenetriam...

The concentrations of 3-methyl-6-methoxy-8-hydroxy-3,4-dihydroisocoumarin (MMHD) formed in carrot roots inoculated with certain fungi or treated with indole-3-acetic acid, 2,4-dichlorophenoxyacetic acid, or 2,4,5-trichlorophenoxyacetic acid (2,4,5-T), were related to the amount of ethylene produced by the root tissue. Ethylene applied exogenously in concentrations above 0.3 ppm induced the form...

Recently, the use of superparamagnetic iron oxide nanoparticles (SPIONS) as a new and promising source of iron in agriculture has been suggested that further investigation is needed before extensive field use. In a greenhouse experiment, the effect of coated magnetite nanoparticles with humic acid (Fe3O4/HA NPs) was investigated on iron deficiency chlorosis and photosynthesis efficiency compare...

The world’s arable land has been contaminated by heavy metals to a large extent, which led the decreasing availability of farmland. Thus, remediation metal pollution deserves due attention, and phytoremediation is preferred. Hemp proposed as an ideal alternative crop for remediating heavy-metal-contaminated soil, owing its well-developed roots, biomass, tolerance metals. Chelators can activate ...

delaying bud break, using chemicals is an approach to avoid spring frost damage. therefore, the effect of spraying different concentrations of soybean oil and naphthalene acetic acid (naa) on delaying bud break, altering internal atmosphere and cold hardiness in grape cultivar ‘fakhri’ was studied in 2011 in a commercial vineyard in maryanaj, hamedan using a factorial trial based on randomized ...

In the present study shacking and incubation experiments were carried out in order to evaluate the changes in heavy metal solubility in the studied soils by addition of different concentration of Ethylene dinitrilo tetra acetic acid (EDTA), Diethylene triamine penta acetic acid (DTPA), and Nitrilo tri acetic acid (NTA). The effects of EDTA, DTPA and NTA application on solubility of Copper (Cu),...
