abstract part one: the electrode oxidation potentials of a series of eighteen n-hydroxy compounds in aqueous solution were calculated based on a proper thermodynamic cycle. the dft method at the level of b3lyp-6-31g(d,p) was used to calculate the gas-phase free energy differences ,and the polarizable continuum model (pcm) was applied to describe the solvent and its interaction with n-hydroxy ...
Salinity negatively influences crop growth, but several salt-tolerant plant species (halophytes) are viable crops. Sarcocornia fruticosa (ecotypes EL and VM) is currently cultivated, there demand for new candidates higher biomass production. Salicornia brachiata Roxb. Arthrocneum macrostachyum L. considered novel crops, to realize their potential, response salinity nitrogen nutrition was compar...
Salinity is one of the major abiotic stresses that affects physiological processes of plants and reduces crop growth and yield. In order to study the effect of salinity stress on some physiological and agronomical traits of Thymus daenensis subsp. daenensis ecotypes and their classification, a factorial experiment was carried out using randomized complete block design with three replications in...
within the components of communicative competence, a special emphasis is put on the “rules of politeness,” specifically the politeness strategies (brown and levinson, 1978) that speakers deploy when performing the request speech act. this is because the degree of imposition that making a request places upon one’s interlocutor(s) has been seen to be influenced by several factors among which, as ...
A study was conducted to investigate structural and functional modifications in three differently adapted ecotypes of Aeluropus lagopoides (Linn.) Trin. ex Thw. under saline conditions. Two ecotypes were collected from moderately saline Bailahwala Dahar (BD) and heavily salt-affected Ladam Sir (LS), respectively while one ecotype was selected from least saline Derawar Fort (DF), which was consi...

Background: Insomnia, which is difficulty in initiating and maintaining sleep, is a very common experience for many people. Considering the increasing interest in medicinal plants in the past decade, many plants such as Coriandrum sativum, Salvia leriifolia, Salvia reuterana and Stachys lavanduli folia have been used in Iranian traditional medicine to abate insomnia. Objective: The present stu...
sardari is one of the most important landraces of common wheat (triticum aestivum l.) that is mainly cultivated in drylands and mountainous area of iran. moreover, it shows a high level of genetic diversity. in the present research a total of 73 sardari wheat ecotypes were evaluated for drought tolerance. genetic diversity was analyzed using amplified fragment length polymorphism (aflp) marker ...
In this study, we examined the antioxidant activities of methanolic extract of three endemic species of Salvia from Iran (S. lachno...
There are mixed reports about the advantages and disadvantages of presence shade produced by trees over understory-growing grasses; thus, it is urgent to test grass species cultivars with potential develop in shaded conditions associated that occur silvopastoral systems. The objective present study was identify Brachiaria spp. ecotypes adapted for cultivation under tree shade, typical conducted...
