for the reproductive success of plants. Plants need to gauge when both environmental and endogenous cues are optimal before undergoing the switch from vegetative to reproductive development. To achieve this, a complex regulatory network has evolved consisting of multiple pathways that quantitatively regulate a set of genes—the floral pathway integrators (Simpson and Dean 2002). The activity of ...
Biofortification (Se): Does it increase the content of phenolic compounds in virgin olive oil (VOO)?
Extra-Virgin Olive Oil (EVOO) is a fundamental component of the Mediterranean diet and it may contain several anti-oxidant substances, such as phenols. Previous research has shown that this food may be enriched in phenols by spraying a sodium-selenate solution (100 mg L-1 Se) onto the crop canopy before flowering. The aim of this research was to evaluate the effect of this Se-fertilization befo...
Application of humic acid as an organic acid derived from humus and other natural resources along with iron could be beneficial to overcoming, at least in part, the nutrients deficiencies in the grapes. In order to evaluate the effects of humic acid and iron on fruit yield and concentration of nutrient elements in the leaf of grape, a factorial experiment based on a randomized complete block de...
The toxicokinetics of salicylazosulfapyridine (SASP) and its metabolites were investigated in male and female B6C3F1 mice either following single intravenous (5 mg/kg) or oral (67.5, 675, 1350, and 2700 mg/kg) doses, or following three consecutive daily oral doses (675, 1350, and 2700 mg/kg). Plasma concentrations of SASP and its metabolites were quantified by HPLC. Upon intravenous administrat...
We investigated the effect of an acute exposure to chlorphenvinphos (CVP), an organophosphate anticholinesterase, on amphetamine-induced open-field locomotion in rats. CVP was administered in a single i.p. dose of 1.0 mg/kg (1/10 of the LD50). All animals were challenged with 1.0 mg/kg amphetamine (AMPH) three weeks after the CVP exposure, i.e. after a time sufficient for acetylcholinesterase r...
In order to optimized nitrogen fertilizer recommendation for a new safflower cultivar called “Padideh” an experiment was conducted in two regions of East Azerbaijan, Tikmehdash and Shabestar. Experimental design was a randomized complete blocks design arranged in factorial with three replications. The first factor was different nitrogen rates including 30, 60, 120 and 180 kg ha-1 nitrogen suppl...
This study was conducted based on a randomized complete block design and a factorial experiment with three replications in regions to investigate the effect of different rates and times of nitrogen on the quantitative properties of safflower. The first factor was different nitrogen rates including 0, 60, 120 and 180 kg ha-1 , and the second one was nitrogen application time including seed sowi...
in the area of vocabulary teaching and learning although much research has been done, only some of it has led to effective techniques of vocabulary teaching and many language learners still have problem learning vocabulary. the urge behind this study was to investigate three methods of teaching words. the first one was teaching words in context based on a traditional method of teaching that is,...
Rosemary (Rosmarinus officinalis L.) is an important medicinal plant that contained a wide range of secondary metabolites such as rosmarinic acid. In this study, essential oil content and composition and rosmarinc acid were determined at three phenological stages (before flowering, full flowering and fruit set stages). Hydro distillation method was used for essential oil extraction and GC and ...
This study was carried out to examine the effect of selected fruit peels on growth and yield okra (Abelmoschus esculentus). 10g ground banana, watermelon, pawpaw, pineapple, plantain, orange applied 7 kg soil left for days before planting seed. NPK (15:15:15) serves as positive control while groups without fertilizer served negative study. Each treatment replicated five times in polythene bags ...
