The percentage and rate of germination and proper establishment of seedlings are important factors contributing to higher yield per unit area. As an essential element for plant growth and development, Zinc plays a critical role in many metabolic processes, and also has a positive effect on seed germination. The effects of seed priming with concentrations of 0.5, 1 and 2 percent zinc sulfate on ...
OBJECTIVES To find a suitable method for detecting zinc sulfate in adulterated urine. METHODS Two rapid spot tests to detect the presence of zinc sulfate in urine were developed. RESULTS Addition of 3 to 4 drops of 1N sodium hydroxide solution to approximately 1 mL of urine containing zinc sulfate led to the formation of a white precipitate, which was soluble in excess sodium hydroxide. In ...
to evaluate the effects of on-farm seed priming treatments and sowing dates on rate and percentage of seedling emergence, biological yield and some physiological indices of corn hybrid (sc. 260) an experiment was conducted in hamedan, iran in 2010. a split plot in a randomized complete block design with three replications was conducted. main plots include three sowing dates (early, on-time and ...
background: industrial copper ingest is a common form of poisoning in animals. zinc has an important role in the physiology of spermatozoa, in sperm production and viability. objective: this study was set to investigate whether the adverse effects of long term copper consumption on quality of rat spermatozoa could be prevented by zinc therapy. materials and methods: forty eight mature (6-8 week...
To study the effects of phosphate and zinc sulfate fertilizers application methods on water use efficiency and qualitative characteristics of corn underwater stress, an experiment was conducted in split plot factorial arrangement on randomized complete block design with three replications at research farm of the Bu Ali Sina University in 2014. Three levels of irrigation after 60, 90, and 120 mm...
In order to study the effect of on-farm seed priming using tap water and zinc sulfate solution with 0.03% zinc on yield and yield components of two intermediate maturing maize cultivars, a factorial experiment was carried out in complete randomized block design with three replications in Research Farm of Bu Ali University, Hamedan, Iran in 2011. Seed priming consisted of three levels (priming w...
بررسی عناصر روی و منیزیم بر خصوصیات زراعی و جوانهزنی بذر گندم نان (Triticum aestivum L. cv. Sivand)
In order to study the effect of zinc and magnesium on agronomic and seed germination traits of wheat (Sivand cultivar), the current study was carried out at Mahidasht Agricultural Research Station in Kermanshah over the years 2012 and 2013. The experiment was conducted as factorial based on completely randomized block design with three replications. The treatments consisted of four levels of zi...
Abstract In this study, effect of spraying nickel sulfate and urea on reproductive growth, yield and some qualitative characteristics of strawberry fruit were investigated. Rooted daughter plants of strawberry, cv. Pajaro, were grown in 3 L pots in greenhouse of College of Agriculture, Shiraz University. The established plants were sprayed, at 4-5-leaf stage, with nickel sulfate at concentrati...
OBJECTIVE To determine the inhibition effect of zinc sulfate on isolates of enteric bacteria. MATERIALS AND METHODS Mueller-Hinton agar containing different concentrations of zinc sulfate was prepared. Isolates used in this study were obtained from local clinics. They were Salmonella typhi, Salmonella groups A, B, C, D and E, Escherichia coli, Enterobacter, Shigella and Vibrio cholerae. Overn...
Reactions of zinc sulfate and (R)- or (S)-(1-phenylethylamino)methylphosphonic acid (pempH(2)) in the presence of 1,4-benzenedicarboxylic acid (H(2)bdc) result in homochiral enantiomers (R)- and (S)-[Zn(4)(pempH)(4)(bdc)(2)].2H(2)O (). When H(2)bdc is replaced by 1,2,4,5-benzenetetracarboxylic acid (H(4)btec), enantiomers (R)- and (S)-[Zn(3)(pempH)(2)(btec)(H(2)O)(2)].H(2)O () are obtained. Com...
