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...

The antioxidant capability, total phenol, total flavonoid, anthocyanins, ascorbic acid contents, and reducing power contents of polar and non-polar extracts for flower and leaves in two stages of growth for Rhamnus kurdica Boiss in flowering were evaluated in this work. The polar extraction of flower of R. kurdica Boiss had a higher total phenolic content as well as antioxidant activity compare...

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...
