پتاسیم قابل استفاده در خاک معیار مهمی برای رشد گیاه و تولید عملکرد است. برخی باکتری های خاک می توانند پتاسیم قابل استفاده را برای رشد گیاهانافزایش دهند. به منظور جداسازی و بررسی میزان کارایی این باکتری ها در خاک، تعداد پنج نمونه خاک از نظر وجود باکتری های آزاد کننده پتاسیم مورد ارزیابی قرار گرفتند و در نهایت شش ایزوله به عنوان باکتری های موثر، جداسازی شدند. براساس بررسی های میکروسکوپی، آزمون ها...
a pot experiment was carried out to determine the effect of foliage spraying of silicon (si) on growth and ornamental characteristics of calendula grown under salt stress and greenhouse conditions. a factorial experiment based on completely randomized design was conducted with 3 levels of si (0, 50 and 100 mg/l) and 3 levels of nacl (0, 100 and 200 mm) with 4 replications. at flowering stage, s...

abstract nitrogen is a key nutrient in plant growth and it is necessary for amino acid synthesis. sulfur has very important role in the biosynthesis of the alliums flavor and pungency precursors and potassium improve crop yield and quality. in order to study the effect of ammonium nitrate and potassium sulfate on concentration some of the mineral elements in onion (allium cepa l. azar shahr cv....
Abstract The expansion of residential areas has increased the demand for exotic and increasingly compact landscape plants. In this context, work aimed to evaluate effects paclobutrazol (PBZ) timing ethylene application on growth reduction flowering anticipation in ornamental pineapples grown pots. randomized block design was used with factorial arrangement (2 x 5) 4 replications plants per plot...
in order to determine yield and physiological response of different wheat genotypes to low temperature, many pot and field experiments were conducted in 2007-2008 at the plant physiology laboratory, university of kurdistan, and ghamlo dryland agricultural research station in kurdistan province. in both experiments, the experimental design was a randomized complete block in a split plot arrangem...
Conducting poly(o-toluidine) (POT) and poly(m-toluidine) (PMT) blends containing 10, 30, 50, 70, and 90 % wt/wt of polystyrene (PSt) were prepared by employing a two-step emulsion pathway. The bands characteristic of both polystyrene and POT/PMT are present in the IR spectra of POT–PSt and PMT–PSt blends. The UV-visible spectra of POT–PSt and PMT–PSt blends exhibit two bands around 313 and 610 ...
147 Individual plant respon~es to herbivory were initially investigated to establish prudent guidelines for livestock grazing on pastures and rangelands. A great deal has been learned concerning the effects of defoliation on the morphology, physiology and productivity of important forage and browse species. However, our perception and understanding of individual plant responses to herbivory hav...
In order to investigate the effect of plant growth promoting rhizobacteria (PGPR) and arbuscular mycorrhizal fungi (AMF) on morphological traits and concentration of macronutrients (nitrogen, phosphorus, potassium, calcium and magnesium) on peppermint medicinal plant, a pot experiment was conducted as complete randomized design with three replications, under greenhouse conditions. Treatments co...
