Copper ore mining and processing release hazardous post-flotation wastes that are difficult for remediation. The studied tailings were extremely rich in Cu (1800 mg kg-1) and contaminated with Co and Mn, and contained very little available forms of P, Fe, and Zn. The plants growing in tailings were distinctly enriched in Cu, Cd, Co, Ni, and Pb, and the concentration of copper achived the critic...

Biofertilizers are used to improve soil fertility and plant production in sustainable agriculture. However, their applicability depends on several environmental parameters. The aim of our study was to evaluate the effect of free-living bacteria containing fertilizer on the growth of cucumber (Cucumis sativus L. cvs. Delicates) under aluminium (Al) stress. Different responses to Al stress of cuc...

introduction: iron overload has been implicated as an important factor for nephropathy by hydroxyl radicals production. on the other hand nitric oxide (no) asa reactive free radical, has numerous effects on kidney. however at high concentration it has been suggested to have toxic effects. in this study the interaction between iron overload and no system on renal function were evaluated in rats....

this research investigate the potential of rhizobium leguminosarum b.v .phaseoli to improve growth and nutritional status of common bean (akhtar cultivar) at three levels of salinity of s0, s1 and s2 (0, 35 and 70 mm sodium chloride, or 0, 3 and 6 ds/m, respectively). the greenhouse experiment was conducted as a factorial design in randomized completely with three replications by using the ster...

Co-Fe films were electrodeposited on Cu substrate from electrolytes with different Co concentration  levels. X-ray diffraction (XRD) was used  to  investigate  the  films  crystal  structures. The  results  indicate that  if  the  Co  concentration  is  less  that  the  Fe  concentration,  the cubic  structure  appears  in  the  films, while  the  hexagonal  structure dominates when  the C...

dog rose (rosa canina) has been using as a rootstock for ornamental roses also it is one of the medicinal plants. it can be propagated under in vitro conditions. after removing chilling requirement of buds, axillary wood buds of dog rose were cut in three nodal positions (lower, middle and terminal) on the stem and then explants after decontamination, cultured on murashige and skoog medium (ms ...
