background & aim: investigating the possibility of using medicinal plant’s seeds substitute for agar gel in plant tissue culture and determining the optimal practical conditions of them is the aim of this study. experimental: in order to study the new gelling agents for using in plant tissue culture, we designed a tow part experiment by means of the seeds of medicinal plants such as linum u...
In order to evaluate the effects of foliar application of micronutrients (iron and zinc) and different harvesting times during seed filling on yield and mucilage percentage of psyllium (Plantago psyllium), a field experiment was carried out in 2009 at the Research Farm of the Faculty of Agriculture, University of Tabriz, Tabriz, Iran. The experiment was arranged as split plot based on randomize...

in the current study, the efficiency of starch and plantago ovata extract as coagulant aids is compared in water turbidity removal. the coagulant is ferric chloride and the experiments are run in two ranges of ph 7 and 8. the achieved results of turbidity removal in different turbidity levels of 100, 50 and 20 ntu caused by different concentrations of starch and p.ovata as coagulant aids besid...
in order to evaluate the effects of drought stress and methanol foliar application on some quantitative and qualitative traits of soybean (cv. viliamz), a split plot experiment was conducted based on randomized complete block design at the faculty of moghan research farm in 2011. treatments were three levels of drought stress based on irrigation at depletion of 40, 55 and 70 percent of availabl...
Rice (Oryza sativa L.) is providing food of half of the world population, and in some regions salinity stress reduces yield of this plant. In order to develop planting of rice in regions with saline water or fields, chlorophyll rate, chlorophyll fluorescence indices and grain yield of some rice cultivars were evaluated in summer, 2012, at the farm of college of Agriculture, at Yasouj University...
we describe here a suitable approach for the synthesis of n-unsubstituted monocyclic b-lactams under mild reaction conditions by the annelation of imines with substituted acetylchlorides. in this method the reaily available phtalimidoacetyl chloride were allowed to react with - dibenzylideneiminotoluene (hydrobenzamide) in the presence of an equimolar amount of triethylamine in refluxing toluen...
abstract tasks nowadays are at the center of attention in sla research. task types is one of the critical issues in this regard, their effectiveness and suitability to any particular context, their characteristics and the result they yield are among some of these issues. on the other hand, discourse markers (dms) have been very much investigated and their effectiveness in conveying the meaning...
Objective: Development of resistance against many of the commonly used antibiotics is an impetus for further efforts to search for new antimicrobial agents. The aim of the study was determined as antibacterial activity of silver nanoparticles produced by Plantago ovata seed extract against Pseudomonas aeruginosa. Methods: All 30 strains of P. aeruginosa wereisolated f...
Background: Researchers are seeking new plant compounds as an alternative to chemical drugs and antibiotics due to the increasing resistance of pathogenic bacteria to antibiotics. This study investigated the antibacterial effect of Plantago ovata and Lallemantia iberica L. seed extracts on some foodborne human pathogenic bacteria. Materials and Methods: Disk-diffusion antibiotic sensitivity te...
