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 ...

fennel (foeniculum vulgare mill.) benefits from a lot of useful medicinal properties. iran is known as one of the main producers of fennel. in spite of high medicinal values, fennel’s cultivation is not economically feasible, mainly due to its low yield. it grows wild in different areas in iran from where diverse ecotypes have evolved. genetic variance and heritability estimates of traits in a ...

background: thymus daenensis is on e of the endemic aromatic species in iran that its essential oil is used in food and pharmaceutical industries. objective: in this study, the effects of plant growth stages and distillation methods on essential oil content and thymol percentage of this species were evaluated. methods: the aerial parts of th. daenensis were collected in three stages of plant gr...

to study the effect of chemical and biological fertilizers on growth and essential oil content of lavender (lavandula angustifolia mill.), the present work was conducted in 2012-2013 at the experimental field of alborz research station of the research institute of forests and rangelands, karaj, iran. the experiment was conducted in factorial in the form of a randomized complete block design wit...

abstract in order to evaluate the effects of different organic and biological fertilizers on quantity and quality of essential oil of fennel an experiment was conducted in a completely randomized block design with three replications. the experimental treatments were two organic (compost and vermicompost) and two biological (pseudomonas putida and azotobacter chroococcum ) fertilizers, their all...

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: Nitrogen is the most important nutrient requirement for plants. Nitrogen supplying affected the leaf area, carbon fixation, glandular trichomes formation, ATP and NADPH content which resulted to the terpenoids biosynthesis enhancement and essential oils accumulation. Objective: This study was aimed to evaluate changes of essential oil content and components by use different levels ...

Background: Thymus daenensis is on e of the endemic aromatic species in Iran that its essential oil is used in food and pharmaceutical industries. Objective: In this study, the effects of plant growth stages and distillation methods on essential oil content and thymol percentage of this species were evaluated. Methods: The aerial parts of Th. daenensis were collected in three stages of plan...

objective: evaluation activity was conducted using three spearmint genotypes (wg-spm-engl, spm-fran and spm-eas) and one standard check (wgsm-03) at wondo genet, awassa, debre zeit and allagae during 2012 and 2013 for two years. methods: the treatments were arranged in randomized complete block design with four replications. data on leaf to stem ratio, leaf yield/ha, essential oil content and e...
