To study the effects of both drought stress and seed zinc and iron concentrations on the photosynthesis, chlorophyll fluorescence, and proline and carbohydrate accumulations in soybean (Glycine max (L.) Merr. cv. M9) leaf, a split plot experiment was carried out in 2012 based on a randomized complete block design with three replications in greenhouse conditions at Yasouj University. Drought str...

A sulfate-encapsulating complex, [Cu(1)L(6)]·3[Cu(2)L(2)(DMF)(4)](SO(4))(4) (1, L = N-(1-naphthyl)-N'-(3-pyridyl)urea) is synthesized in which two C(3)-clefts of the octahedral complexes interdigitate to form a cavity to encapsulate the sulfate ion by six urea groups.

zno nanoparticles were synthesized by a microwave-assisted chemical method. zno nanostructures were synthesized via a fast reaction between zinc acetate and ammonia at presence citric acid and other effective agents in chemical procedure. nanostructures were characterized by x-ray diffraction , scanning electron microscopy. seed yield and seed quality of safflower grown under drought stress. th...

The hyper yield of peroxidase (POX) was investigated for a novel native Aspergillus niger strain identified by 18S RNA analysis. A. strains sequences were submitted to GenBank; IDs allotted MN611114.1 (BMB 17) and MN559756.1 (BMB-18). in combination showed enhanced activity (601.5 U/mL) solid-state fermentation comparison their individual activities. POX purified ammonium sulfate, size exclusio...

BACKGROUND Iron, zinc, and calcium can interact with each other in a way that inhibits their respective absorption. On the other hand, mineral fortification has been used to improve simultaneous iron and zinc absorption from food supplements. OBJECTIVE We evaluated the effect of a novel fortificant mixture consisting of NaFeEDTA, zinc methionine, ascorbic acid, and citric acid on iron and zin...

To assessment growth physiological charachteristics of two hybrids of sweet corn affected different irrigation pattern and zinc fertilization, a research was conducted as split plot factorial experiment based on randomized complete blocks design with three replications. Main factor included different levels of irrigation pattern included conventional furrow irrigation, fixed every other furrow ...

The preflood nitrogen (N) fertilizer sets the yield potential of the rice cultivars being grown and thus, its management is critical to obtaining profitable rice grain yields. The objectives of this study were to evaluate the ammonia volatilization loss and impact on rice yield when urea, Agrotain®, and ammonium sulfate were applied preflood and a flood established at 1, 5, and 10 days after N ...

Background: Since cellular membranes play key role in the physiological pathways of the cell, such as fertilization through almost every cellular function to cell division, it is very important to assess the structural and functional activity of the sperm membrane. In this study, a new method for measurement of sperm membrane stability measured the amount of zinc which liberated after being exp...
