abstract due to calcareous soil conditions, zinc deficiency is a yield limiting factor for wheat production in iran. one solution for this problem is the cultivation of zn-efficient wheat varieties. ten wheat cultivars (nine bread wheat and one durum wheat) with different tolerance to zn deficiency were studied in a greenhouse experiment. plants were treated with zn (10 mg zn kg-1 soil as znso4...

objective: zinc is the second main element in the body after iron. its importance in pregnancy is related to role in dna and protein synthesis and consequently the necessity of its availability for the appropriate growth and development of the fetus and neonate. the purpose of this study was to assess the effect of zinc supplement on fetal outcomes (height, weight, head and chest circumference ...

abstract soil pollution with heavy metals like zinc causes increasing concerns about environment. according to distribution in soil, this study was conducted to compare zinc concentration between aggregate exteriors and interiors of some contaminated soils. aggregates were collected from 5 depths of 4 soil profiles with different textures and were separated mechanically into exterior and interi...

Human and rabbit ocular tissues contain high concentrations of zinc. In descending order in human globes, the metal concentration appears to be: retina-choroid, ciliary body, iris, optic nerve, sclera, cornea, and lens. Diamox does not alter the concentration of ocular zinc. In preliminary studies dithizone, a known zinc chelator, does not appear to alter ocular zinc concentration as well. The ...

in order to investigate the effect of zinc element application on growth and some morphophysiological of maize (single cross 704) an experiment was conducted during 2010 at greenhouse. experimented design was complete randomize factorial with four replications. treatments of experiment were soil salinity (4, 8 ds.m-1 and 0 as a control) and different zinc concentration including 0, 10 and 20 mg...

conclusions: it was concluded that increasing the concentration of zinc in the agricultural soil is harmful to beneficial microorganisms and reduces the soil fertility. a 20-ppm zinc concentration in soil is suggested to be optimal. background: zinc is an essential micronutrient used in the form of zinc sulfate in fertilizers in the agriculture production system. nitrogen-fixing microorganisms ...

To obtain rich in organic forms of zinc extracts of Lentinus edodes, possessing putative higher immunostimulating properties than actually used, mycelia were cultivated in zinc(II) enriched media. Culture media were enriched in zinc in concentration ranging from 0 to 90 microg mL(-1), added to the medium before inoculation. Total zinc concentration in submerged cultivated mycelial biomass has b...
