The effect of exogenous application of nano-iron chelate (100 and 200 mg/l) in early flowering stage on components of essential oils (EOs) of Carum copticum was evaluated. The EO extracted by hydrodistillation from Iranian C. copticum was characterized by means of GC/MS. The nano-iron chelate application increased γterpinene and thymol and decreased α-pinene, β-pinene and p-cymene concentration...

ornithine is a non-proteinogenic amino acid, which plays an essential role in the metabolism of plants. regard to the chirality of the molecule, physiological response of the plant cells to its two enantiomers have not been widely investigated yet. in the present study, suspension-cultured tobacco cells were treated with 1 mm of d- and lenantiomers of ornithine in normal conditions as well as u...

During our screening program for agrochemicals from Chinese medicinal herbs and wild plants, the essential oil of Carum carvi fruits was found to possess strong contact toxicity against Sitophilus zeamais and Tribolium castaneum adults, with LD₅₀ values of 3.07 and 3.29 μg/adult, respectively, and also showed strong fumigant toxicity against the two grain storage insects with LC₅₀ values of 3.3...

Coriandrum sativum L. has a distinct flavour and aroma which is due to the essential oil present in it. The main component of the essential oil of the fruit is monoterpenoids and linalool. All parts of the plant are edible. The content and composition of essential oil is influenced by climatic conditions, agro technology and stage of maturity at time of harvesting, geography of growing region, ...

zinc has previously been reported to alleviate salinity stress in plants. in this study, we monitored various biomass and chlorophyll fluorescence parameters to determine the optimum zinc sulfate concentration that can be used as foliar spray to alleviate salinity stress in glycine soja. the plants subjected to a series of salinity levels (nacl concentration of 0, 100, 200, and 300 mmol l-1), a...

considering the extent of salinity in soils of iran, abiotic stresses such as salinity are serious threat to agricultural production, yield and essential oil of medicinal plants. recognition of threshold for salt tolerance and determining the slope of yield loss in medicinal plants has an important role in the selection of suitable lands for their cultivation. the effect of salinity stress on s...
