black seed is one of important ancient medicinal plants with various properties in traditional medicine. in order to evaluate microelements (fe and zn) effects on seed yield and yield components of black seed in salinity stress, a complete block design with three replications was conducted in esfahan agricultural and natural resources center during 2013-2014. three water salinity treatments wer...

abstract- to evaluate effects of different soil moisture conditions namely, phosphorus (p) and zinc (zn) application, on extractable zn and fe, two experiments were conducted in laboratory conditions based on a completely randomized design with a factorial arrangement of treatments with two replications. the first experiment was performed with the following factors; incubation time at four leve...

the 440 fertile eggs, in a completely randomized design were divided into 11 treatments with four replicatesand 10 eggs per each replicate. treatments including: (t1; control; without injection), (t2; injected with 0.3ml saline 9.0%; sham control), (t3, t4 and t5) 25, 75, 125 ppm fe-nano, (t6, t7 and t8) 50, 100, 150 ppmfe-nano-alimet chelate, (t9, t10 and t11) 50, 100, 150 ppm fe-aliment chela...

influence of arbuscular mycorrhizal fungi (amf) (glomus etunicatum, g. intraradices and glomus versiforme) and external phosphorus supplement (8 and 35 mg p kg-1 soil) on leaf p, zn, cu and fe nutrition of 4-month-old tea(camellia sinensis) was studied in an glass house pot experiment. the highest leaf p concentration (up to 59.43% increase) was found in g. versiforme inoculated seedlings gro...

I. Rats were made severely iron-deficient by feeding with Fe-deficient diets, which contained adequate amounts of zinc. 2. Ten days after an oral dose of 250 ,ug %n the Fe-deficient rats had retained 17 yo whereas control rats had retained only 8 yo of the dose. 3. When unlabelled Zn was given intravenously to the Fe-deficient and control rats there was a reduction in retention of the orally ad...

Nearly half of the world cereal production comes from soils low or marginal in plant available zinc, leading to unsustainable and poor quality grain production. Therefore, the effects of nitrogen (N) rate and application time on zinc (Zn) and iron (Fe) concentration in wheat grain were investigated. Wheat (Triticum aestivum var. Krabat) was grown in a growth chamber with 8 and 16 h of day and n...

in order to study concentrations of soil micro and heavy metal elements in some saffron planting regions of birjand province, an experiment was performed as factorial layout based on a completely randomized block design with three replications at year 2013. treatments were three field ages (annual, triennial and quinquennial) and five saffron regions including aryan shahr, hosseinabad, khosef, ...

18 1 (mean 28 mg kg). Spring wheat cultivars pos19 sessed higher Fe-grain concentrations than winter 20 wheats. By contrast, winter wheats showed higher 21 Zn-grain concentrations than spring genotypes. 22 Within spring wheat, a strongly significant positive 23 correlation was found between Fe and Zn. Grain 24 protein content was also significantly (P < 0.001) 25 correlated with grain Zn and Fe...
