In order to study the effect of different levels of the manure and foliar application of Zn and Mn fertilizers on the quantitative and qualitative yield of soybeans (var. Williams), a factorial experiment was conducted in a randomized complete block design with three replications in 2012. Treatments involved three levels of fertilizer: manure (zero as control; six and 12 t/ha), two lev...

Many metal transporters in plants are promiscuous, accommodating multiple divalent cations including some which are toxic to humans. Previous attempts to increase the iron (Fe) and zinc (Zn) content of rice endosperm by overexpressing different metal transporters have therefore led unintentionally to the accumulation of copper (Cu), manganese (Mn) and cadmium (Cd). Unlike other metal transporte...

Plant species with the capacity to tolerate heavy metals are potentially useful for phytoremediation since they have adapted to survive and reproduce under toxic conditions and to accumulate high metal concentrations. Gomphrena claussenii Moq., a South-American species belonging to the Amaranthaceae, is found at a zinc (Zn) mining area in the state of Minas Gerais, Brazil. Through soil and hydr...

the essential nutrients in the pharmacological plants play a significant role in the remedy of illnesses but, these elements at high levels; can also be dangerous and toxic. the aim of this study was to determine the concentration of macro (mg, ca, p, and k) and micro (cu, zn, fe and mn) essential elements in seven indigenous pharmacological plants growing in fars province, southern iran. they ...

concentrations of eight metals namely, cr, mn, fe, co, ni, cu, zn and pb were examined in the surface sediments of discharge channels of six industries in lagos using x-ray fluorescence spectrometry.these channels drain into the isolo canal which empties into the lagos lagoon and eventually into the atlantic ocean. this study was conducted to detect any contamination levels within the sediments...

Phytoremediation using woody plants can effectively reduce heavy metal (HM) concentrations in soils. However, the remediation capacity of depends greatly on plant species and soil environmental conditions. In order to evaluate HM potential from different tailing areas, accumulation characteristics roots, shoots, leaves 12 dominant native growing iron lead-zinc areas were analyzed. The results s...
