nowadays soil contamination with heavy metals is considered as one of the most serious environmental concerns. among the heavy metals, lead due to inverse impacts on human health and substantial environmental problems causes major concern.this study was carried out with the aim of assessing the ability of different corn cultivars in a greenhouse condition for the accumulation of lead metal. tre...

the so-called phytoextraction in which hyperaccumulator plants are used to remediate the contaminated soils is proven to be an efficient method. the objective of this study was to investigate the capability of spinach for phytoremediation of cadmium from cd-contaminated soils and determine the efficiency extent of spinach for phytoremediation. for this purpose, a randomized block experimental d...

Plant growth regulators, especially those applied directly to the root system, are thought to significantly reduce growth of the root systems. Various perennials were treated with uniconazole (Concise, Fine Americas, Inc.) to evaluate effects on plant height as well as shoot and root dry weights. Plant height of Lobelia cardinalis was not affected by a 1 ppm uniconazole liner dip, but shoot dry...

in this study the effects of some soil properties on uptake arsenic and cadmium by silybum marianum was studied. to this end surrounding area asphalt plant of city kalaleh, was divided to 6 pieces (a, b, c, d, e, f), with an area of approximately one hectare. plots a and d on both sides of the river, are the nearest areas asphalt plant. also a non-polluting area as a control was considered. ars...

The use of recent technologies for the increase of growth indexes and the plants yields is an important aspects and till now many research works for this has been done. One of these efforts is the usage of magnetic water and zeolite for the increase of yield plants. This research work is an study on the effects of magnetic water and zeolite that has been done on frame work of pore random design...

the effect of different isolates of trichoderma namely t. virens t65, t virens t90, t. virens t96, t. virens t122, t. brevicompactum t146, t. koningiopsis t149, t. viridecense t150, t. koningii as well as two trichodermin b and subtilin commercial bioproducts on growth promotion in wheat were studied through seed coating method in a compeletly randomized design in a glasshouse experiment. the i...

Agrobacterium rhizogenes (pRi), a causative agent of hairy root disease, effectively induces hairy root formation in a variety of plant species. In our study four bacterial strains AR15834, A4, 9435 and C318 and three explants types leaf, stems and roots, were examined. Hairy roots were induced from roots, stems and leaf explants. The highest transformation efficiency of 77% was achieved by usi...
