The essential oils of three wild-growing Thymus species, collected from west of Iran during the flowering stage, were obtained by hydrodistillation and analyzed by gas chromatography (GC) and gas chromatography/mass spectrometry (GC-MS). Under the optimum extraction and analysis conditions, 44, 38, and 38 constituents (mainly monoterpenes compounds) were identified in T. kotschyanus Boiss. and ...

The aim of the present research is to investigate the profile of amino acid of Chlorella vulgaris supplemented with some plant amino acid and oil extracts. The bioactive oil and amino acid from four Iranian medicinal plants, namely Oliveria decumbens, Thymus kotschyanus, Trachyspermum ammi, and Zataria multiflora were obtained. The LC-MS / MS analysis demonstrated that the major amino acids com...

in this study, anti alternaria solani effects of essential oils of 11 medicinal and aromatic plant species belonging to four families collected from the west of iran were investigated based on agar dilution method with five replications at concentration of 1.0 µl/ml. the results showed that the highest inhibitory effect belonged to oliveria decumbens, cinnamomum zeylanicum, carum copticum and t...

The introduction of nanoparticles into seed germination and seedling growth of plants might have a significant impact and thus, it can be used for agricultural applications for better growth and yield. The purpose of this study was to compare the effects of silica and silver nanoparticles on seed germination and early growth traits as well as percent and rate of germination, root length, shoot ...

Growth and productivity of plants are mainly affected by various environmentalfactors in different ecosystems and natural habitat in the world. This research aims to studythe existing relationships between the phytosociology characteristics of Thymuskotschyanus and environmental factors in order to find the most important factorsgoverning development of the species in middle Taleghan rangelands...

plant diversity conservation is a main objective in rangelandmanagement. plant diversity is a suitable index for showing the changes ofvegetation in rangelands and has a high correlation with ecosystem parameters.therefore, using this index it is possible to find the changes and manage theecosystem correctly. the current research was performed to determine the speciesdiversity in fashandak rang...
