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...

Cymbopogon flexuosus (Steud.) cv. Suvarna produces an essential oil with unique lemon like aroma which is broadly used in flavors, fragrance, perfumery and pharmaceuticals. Here we report changes in essential oil content and compositions during C. flexuosus cv. Suvarna leaf development, leaf positions and leaf age. Essential oils were isolated by hydro-distillation of leaves harvested at six di...

chrysanthemum cut flower is not sensitive to ethylene and its vase life depends on vascular blockage. in order to evaluating of effect of antibiotics and essential oils on the vase life and quality characteristics of chrysanthemum cut flower an experiment carried out based on a rcd with 10 treatments: artemisia at 3 levels (10, 30 and 50 %), amoxicillin at 3 levels (100, 200 and 300 mg l-1), ri...

In order to study the effects of humic acid foliar spraying on morphological traits, photosynthetic pigmentation, and essential oil content of Dracocephalum moldavica, a factorial experiment was conducted based on a randomized complete block design with three replications in Saveh. The investigated factors included the use of humic acid at four levels 0 (control), 200, 400, and 800 mg/L and eth...

Dracocephalum moldavica L. is an annual species of Lamiacea family whose essential oil is widely used in medicinal, food, cosmetic and health industries. Drought stress is a major factor limiting plants growth and yield. The main objective of this study was to evaluate the influence of irrigation regime on essential oil content and composition of D. moldavica L. The Irrigation regimes were 100%...

In order to study the response of concentration and composition of essential oil of coriander (Coriandrum sativum) to cattle manure and nitrogen fixing bacteria, an experiment was conducted as factorial experiment in the base of randomized complete blocks design with twelve treatments and three replications at homand research station in Damavand of Iran in 2010. The factors were cattle...

Background: Summer savory (Satureja hortensis L.) is one of the most important medicinal and spice plants cultivated in many parts of the world. Objective: A greenhouse experiment was conducted to study the effects of FeSO4 and citric acid application on the morphological traits and essential oil content and its component, gamma-terpinene in S. hortensis. Methods: FeSO4 in four levels (0, 3, ...

Study the effects of inoculation with two arbuscular mycorrhizal (AM) fungi, Gm (Glomus mosseae T.H. Nicolson & Gerd.)Gerd & Trappe) and Gi (Glomus intraradices  N.C. Schenck & G.S. Sm.) on the  herb yield, essential oil (EO) content and nutrient acquisition of basil (Ocimum basilicum L.) under drought stress conditions,The experiment conducted with 9 treatments and 4 replications. Drought stre...
