Among abiotic stresses, drought is considered as the most important growth limiting factor, especially in arid and semiarid regions. Drought impacts can be adjusted by soil microorganisms. Accordingly, the present study was organized in order to the increase the tolerance of lemongrass (Cymbopogon citratus)to drought using plant growth promoting rhizobacteria (PGPR). Treatments were wa...
Introduction: Salinity is a basic non-living environmental factor that reduces the yield worldwide. In arid and semi-arid regions, the salinity of water and soil limits crop production. Therefore, it is crucially important to assess the salinity tolerance of medicinal herbs if they are to be cultivated in saline areas. Materials and Methods: To investigate the effect of water salinity and so...
Cronobacter sakazakii is a foodborne pathogen associated with fatal forms of necrotizing enterocolitis, meningitis and sepsis in neonates and infants. The aim of this study was to determine whether citral, a major component of lemongrass oil, could suppress putative virulence factors of C. sakazakii that contribute to infection. Sub-inhibitory concentrations of citral significantly decreased mo...
BACKGROUND In aromatherapy, essential oils are used as anti-inflammatory remedies, but experimental studies on their action mechanisms are very limited. AIMS OF THE STUDY To assess their anti-inflammatory activities, the effects of essential oils on neutrophil recruitment in mice were examined in vivo. METHOD The effect of essential oils on leukocyte and neutrophil recruitment induced 6 h a...
Micron-sized gold plates were prepared by reducing chloroauric acid with lemongrass extract. Their two-photon luminescence (TPL) and second harmonic generation (SHG) were investigated. The results show that the TPL and SHG intensity of gold plates is dependent on the wavelength and polarization of excitation laser. The TPL intensity of gold plates decreases with the increase of the excitation w...
بیماری پژمردگی باکتریایی یا پوسیدگی قهوه ای سیب زمینی یکی از مهم ترین بیماری های خاکزاد سیب زمینی از نظر گسترش و میزان خسارت می باشد. عامل بیماری نژاد3 /بیوار 2 باکتریralstonia solanacearum است. امروزه کنترل بیماری های گیاهی با روش های سازگار با محیط زیست از اهداف مهم متخصصین علم بیماری شناسی گیاهی است. به منظور کنترل بیماری یاد شده، از مناطق سیب زمینی کاری منطقه جیرفت (جنوب استان کرمان) بازدید...
