to investigate the effects of mycorrhizal fungi, phosphatic biofertilizer and manure application on yield and quantitative and qualitative criteria of coriander an experiment was conducted at khoramabad during growing season of 2013. the experiment design was applied as factorial layout based on a randomized complete block design with 18 treatments and three replications. the factors were mycor...

Bcakground: Extracts obtained from natural sources such as plants are of immense importance for humans. Methods: Therefore this study was conducted to obtain essential oil from the seeds of T. ammi by conventional and non-conventional methods. Hydrodistillation (HD), Solvent Extraction (SE), Ultrasonication (US), and Supercritical Carbon-dioxide (SC-CO₂) extraction techniques were used to extra...

Background: Essential oil content and composition in medicinal and aromatic plants is highly affected by both biotic and abiotic factors. Objective: To investigate the effects of drought stress, zeolite and bio-fertilizers on morphological characteristics and essential oil constituents in Dracocephalum moldavica L. Methods: This experiment was conducted in the form of split factorial based on...

using medicinal plants as drug or spice in food have significantly increased in recent decades. also, production of this plants restricted by drought stress. therefor the aim of this was investigation of drought stress effect on fruit and essential oil yield of different endemic coriander genotypes. in this regard, 14 coriander genotypes subjected to two levels of water treatments in two separa...

The chemical composition of the essential oil obtained from aerial parts of Galium verum L. (Rubiaceae) from Iran was examined by a combination of GC and GC/MS. The oil isolated by hydro-distillation using a Clevenger-type apparatus. Air-dried aerial parts of Galium verum (80 g) which were collected from Bomehen in Tehran province at full flowering stage on May 2003, were subjected to hydro-dis...

in order to compare planting season effect on agronomic of characters and yield of dill (anethum graveolens l.) an experiment based on completely randomized design with three replications was conducted in 2006-07 in esfahan province and three planting seasons (spring, summer and autumn) were evaluated. essential oil compositions were obtained by clevenger and recognized by gc-mass and gc. accor...

there is little information available on morphological and agronomic traits, as well aschemical compositions of iranian mint landraces. this study was conducted to investigate themorphological, agronomic and oil content characteristics of iranian mint landraces using twelvelandraces, three of which belong to mentha longifolia, and the remaining, mentha spicata l, originatedfrom central regions ...

Background & Aim: Sweet basil (Ocimum basilicum), a plant that is extensively cultivated in some countries, is used to enhance the flavour of salads, sauces, pasta, confectioneries and other products as both a fresh and dried herb. The effect of foliar application of Jasmonic acid and reduced irrigation on essential oil yield and chemical components of two Iranian landrace of basil (<e...

     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...

in this research, effect of vermicompost and plant growth promoting rhizobacteria (pgpr) on physiological traits of lemon balm under drought stress condition was investigated in year 2012 at karaj research institute of forest and rangelands. experiment was conducted as split-split plot in a randomized complete block design with three replications. irrigation (normal: irrigated to field capacity...
