The most important characteristic of stevia is its high sweetness with zero calories which is due to the presence of Steviol glycosides (SVglys). This research aims to address the effect of salicylic acid (SA) and microelements viz. iron (Fe) and zinc (Zn) under different soil water potentials (-0.5, -3.5, -6.5 and -10 atm) on the production of SVglys and total sugar content in the leaves o...

We report first-principles calculations for Fe4Al11-x where 0 ≤ x ≤ 3 and for Fe4Al11-yZny for 0 ≤ y ≤ 1. We investigate the correlation of the magnetic and vibrational behavior with the density of states at the Fermi level. For Fe4Al11-x the magnitude of the magnetic moment correlates with the number of Fe in the chains. However we also find an intrinsic contribution to the magnetism associate...

The fortification of cereal grains with metal micronutrients is a major target to combat human malnutrition of Fe and Zn. Based on recent studies showing that N fertilization can promote Fe and Zn accumulation in cereal grains, we investigated here the influence of nitrate- or ammonium-based N fertilization on the accumulation of Fe, Zn, and Cu as well as metal chelator pools in flag leaves and...

To minimize injury due to water stress, plants have developed multiple strategies by which they resist. Hence, Fe and Zn were researched in relation the influence of drought stress, because, they are the most frequently minerals lacking in human diet especially in the semiarid regions such as Northeast Brazil. A large variability was observed in the zinc and iron content of 100 sorghum genotype...

The present paper studies the content of heavy metals: Fe, Mn, Zn, Cu, Pb, Ni and Cd in the foliage of an indicator plant dandelion as collected from the lawns and parks of the Warsaw metroplitan area. The results suggest heavy accumulation of Fe, Zn, Pb and Cd as a consequence of the impact of traffic-born pollution. Keywords! dandelion, indicator plant, zinc, copper, iron, lead, cadmium, poll...

The aim of this study was to perform ICP analysis of the content of Pb, Mn, Cu, Zn, Fe, K, Na, P, MgandCa in wildediblemushrooms Boletus pinophilus. The samples were collected from the Batak mountain, Bulgaria. The preparation of samples was done by microwave mineralisation. Allmineral concentrations were determined on a dry weight basis (d.w.). The average content of studied elements: Pb, Mn, ...

The mineral content of legumes is generally high, but the bioavailability is poor due to the presence of phytate, which is a main inhibitor of Fe and Zn absorption. Some legumes also contain considerable amounts of Fe-binding polyphenols inhibiting Fe absorption. Furthermore, soya protein per se has an inhibiting effect on Fe absorption. Efficient removal of phytate, and probably also polypheno...

Elevated inorganic phosphate (Pi) concentrations in pore water of amended tailings under direct revegetation may cause toxicity in some native woody species but not native forbs or herb species, all of which are key constituents in target native plant communities for phytostabilizing base metal mine tailings. As a result, Pi sorption capacity has been quantified by a conventional batch procedur...

to study the effect of nitrogen form and ph of nutrient solution on the uptake and concentration of fe, zn, cu and mn in roots and shoots of spinach plant, a factorial experiment was conducted with two factors including nutrient solution ph in three levels (4.5, 6.5 and 8.0) and nitrate to ammonium ratio of nutrient solution in five levels (100:0, 75:25, 50:50, 25:75 and 0:100). the experiment ...
