نظام تلفیقی تشخیص و توصیه میتواند بهعنوان روشی مؤثر در تفسیر نتایج تجزیه گیاه در محصولات زراعی و باغی مورد استفاده قرار گیرد. برای تعیین ارقام مرجع این نظام در پیاز (Allium cepa L.) نمونههای برگ از 50 مزرعه جمعآوری و غلظت عناصر غذایی N، P، K، Ca، Mg، Fe، Mn، Zn، Cu و B تعیین شدند. با توجه به عملکرد محصول، مزارع به دو گروه با عملکرد زیاد و کم تقسیم شدند. ارقام نظام تلفیقی تشخیص و توصیه برای...
In order to investigate the seed vigor of corn hybrid 704 after maternal plant foliar application with methanol, some micro and macro-nutrients an experiment was conducted in a factorial form based on RCBD with three replications during growing seasons of 2010-2011. Treatments were four growth stages (the 8-10 leaves, the tasseling, the seed-filling, all the stages), seven levels of foliar appl...
Manganese (Mn) is an essential metalloenzyme component that in high doses can exert serious oxidative and neurotoxic effects. The aim of this study was to investigate the potential effect of the antioxidant L-cysteine (Cys, 7 mg/kg) on the adult rat brain total antioxidant status (TAS) and the activities of acetylcholinesterase (AChE), Na+,K+-ATPase and Mg2+-ATPase induced by short-term Mn admi...
سیستم تلفیقی تشخیص و توصیه (dris) می تواند به عنوان روشی مؤثر در تقسیر نتایج تجزیه گیاه و نیازهای غذایی محصولات زراعی و باغی مورد استفاده قرار گیرد. برای تعیین اعداد مرجع dris در چغندرقند، نمونههای برگ از 57 مزرعه چغندرقند در استان آذربایجان غربی جمعآوری، و غلظت n، p، k، ca، mg، fe، zn، mn، cu و bآنها تعیین گردید. مزارع با توجه به مقدار عملکرد، به دو گروه مزارع با عملکرد بالا و پایین تقسیم ش...
OBJECTIVE Both superoxide dismutase (SOD), a free radical scavenger, and nitric oxide (NO), a vasodilator with anti-inflammatory properties, have been shown to protect the myocardium from reperfusion injury. They are known to interact in vivo, the influence of which on myocardial protection has not been studied. METHODS Four groups of rats (n=7, per group) were subjected to experimental infar...
In order to investigate mineral manganese forms and their relations with plant responses, 22 soil samples from Fars province (0-20 cm) were in a greenhouse experiment filled in 3 liter pots, and soybean (Glycine max (L.) merr.,CV.Williams) was grown for 7 weeks. Chemical forms of manganese were determined in soils by warden and Reisenauer sequential extraction method (readily soluble, weakly ad...

The complex [Mn(dbm)(2)(py)(2)](ClO(4)) (dbm = anion of 1,3-diphenyl-1,3-propanedione (dibenzoylmethane), py = pyridine) was synthesized and characterized by X-ray crystallography. It has tetragonally distorted geometry with the axial positions occupied by the py ligands and the equatorial positions by the dbm ligands. This mononuclear complex of high-spin Mn(III) (3d(4), S = 2) was studied by ...
