The potential of three arbuscular mycorrhizal fungi (AMF) - Glomus mosseae, G. fasciculatum and G. intraradices- to enhance the production of essential oil and plant growth parameter was investigated in sweet basil (Ocimum basilicum). The AMF inoculation significantly increased plant height, fresh and dry matter yield, oil content and oil yield as compared to non-inoculated basil plants. Essent...

This experiment was conducted in 2012 at the research field of Alborz Research Station, Research Institute of Forests and Rangelands, Karaj, Iran, to study the effect of chemical and biological fertilizers on Sage (Salvia officinalis L.) and replacing biofertilizers instead of high doses of chemical fertilizers. The experiment was conducted in factorial in the form of a randomized complete bloc...

this study was conducted to determine the effect of foliar salicylic acid (sa) and citric acid (ca) applications on growth, biochemical characteristics and essential oil content of thyme (thymus vulgaris l.) grown under field conditions. salicylic acid (0.5 and 1 mm) and citric acid (5 and 10 mm) were applied three times during the vegetation at 15 day intervals. results revealed that foliar ap...

Background & Aim: Essential oil of pennyroyal (Mentha pulegium L.) has many applications in food, perfume and pharmaceutical industries. The aim of this study was to determine the content and chemical constituents of pennyroyal essential oil growing wild in Southern Iran. Experimental: The aerial parts of the plant were collected around Hajiabad, Hormozgan province in 2013. The essent...

the essential oil obtained by hydrodistillation of the aerial parts of rosa damascenea mill. was analyzed by gc/ms. the yield of the oil was 0.16% (v/w). among twenty five components, eight components, representing 99.98% of the oil, were characterized. nonadecane (39.73%), heneicosane (32.38%), docosane (7.34%), citronellol (6.14%) and 9-nonadecene (5.69%), were found to be major constituents.

The essential oil of Helichrysum italicum significantly reduces the multidrug resistance of Enterobacter aerogenes, Escherichia coli, Pseudomonas aeruginosa, and Acinetobacter baumannii. Combinations of the two most active fractions of the essential oil with each other or with phenylalanine arginine beta-naphthylamide yield synergistic activity. Geraniol, a component of one fraction, significan...

in order to evaluate the effects of different plant densities and nitrogen levels on growth, yield and qualitative characteristics of marigold, a field experiment was conducted as split plot based on randomized complete block design with four replications at the agricultural research station, azad university of torbat-e-jam, during growing season of 2008-2009. main and sub plots were four nitro...

The relative proportions of chemical classes (hydrocarbons, oxides, alcohols, ketones, esters) in the essential oil of rosemary (Rosmarinus officinalis L., Lamicaeae) and in the volatile fraction of the infusion extracts were examined and showed remarkable differences.The volatile compounds of the infusion were isolated by two different methods, hydrodistillation and solid phase extraction (SPE...

  Background: Essential oils and various extracts from plant are of great interests in the industry and scientific research.   Objective: This study was designed to examine the chemical composition of essential oil and of Echinophora platyloba from Iran.   Method: The chemical composition of the hydrodistilled essential oil of the air-dried aerial parts of Echinophora platyloba growing wild in ...
