In this study, the efficacy five EOs obtained from O. decumbens, T. daenensis, S. sahendica, khuzistanica rechingeri , was evaluated against three insects economic relevance, mosquito Culex quiquefasciatus housefly Musca...

The present study examined the effects of foliar spray selenium nanoparticles (0, 10 and 20 mg/L) on yield, phytochemicals essential oil content composition pineapple mint (Mentha suaveolens Ehrh.) under salinity stress 30, 60 90 mM NaCl). Obtained results demonstrated that severe reduced fresh weight (FW) plant height (PH) by 16.40% 19.10%, respectively compared with normal growth condition. On other hands, sever relative water (RWC) chlorophyll index were 18.05% 3.50%, respectively....

The current research was conducted to compare the growth, yield, and phytochemical composition of basil (Ocimum basilicum) in open field soil hydroponic cultivation a greenhouse. Furthermore, effect foliar spraying micronutrients on this crop also evaluated. In each systems, one micronutrient, either iron sulfate (Fe), zinc (Zn), copper (Cu), manganese (Mn), or boric acid (B), at concentration 0.1% applied randomized complete block design. Plants grown system had higher yield biomass....

Origanum vulgare, a popular flavoring herb, is valued for several biological properties. The present study focused on the chemical composition and antioxidant activity of essential oils vulgare subsp. gracile in different plant parts at phenological stages. Qualitative quantitative analyses oil identified 41 constituents that varied with age organ. phenolic monoterpenoid carvacrol (18.1–79.2%) was predominant all samples. Other major were p-cymene (3.9–18.0%), γ-terpinene (0.9–15.8%), methyl...

Boiss., an endemic and endangered medicinal aromatic plant in Iran, showcases distinct botanical characteristics therapeutic promise. According to the IUCN grouping criteria, this is facing challenges due overcollection from its natural habitats. To address issue, there increasing inclination towards cultivating species within agricultural systems. This study aimed evaluate impact of applying Fe

Satureja khuzistanica Jamzad is a valuable and endemic medicinal plant. Boron zinc are essential elements for the vegetative reproductive growth of plants have significant effects on yield, oil composition seed production plants. To investigate foliar application boron growth, phytochemical properties S. khuzistanica, study was conducted in factorial experiment with three replicates two consecutive years based randomized complete block design. The (B) at concentrations (control or distilled...

The different wavelengths of solar radiation incident on earth [herein: Photosynthetically Active Radiation (PAR) , Ultra Violet-A (UV-A) and Violet-B (UV-B)] their spectral balance not only have an impact plants' growth, morphology physiology, but also are important for the quality quantity plant secondary metabolites.In outdoor study we addressed effects PAR intensity UV-A UV-B yield, phenolic flavonoid content, antioxidant activity essential oil composition Pelargonium graveolens L'Hér....

The composition and in vitro antibacterial activity of essential oils from four Satureja species (S. bachtiarica, S. khuzistanica, mutica rechingeri) growing Iran were determined. According to the results GC–FID GC–MS analysis, all oil samples principally composed phenolic constituents (carvacrol and/or thymol) with percentages ranging 41.2% bachtiarica) 77.7% rechingeri). Determining activities by disc diffusion method against two Gram-positive Gram-negative bacteria revealed maximum...

Solar ultraviolet (UV) radiation mainly includes UVA (320–400 nm). intensity varies depending on the season and geographic location, while it is projected to rise owing climate change. Since elicits secondary metabolism, additional knowledge dependence of phytochemical production required for both farmers processors, particularly under natural settings. In this field study, pheno-morphological traits essential oil composition responses were addressed in three Thymus species [T. daenensis...
