Rhizosphere soil microorganisms are significant factors affecting plant growth, especially that of saline–alkali tolerant plants in the desert ecosystem. We performed high-throughput sequencing order to identifying fungal community structures and their relationships physicochemical properties different layers for plant, Anabasis aphylla, its natural environment. The number unique operational ta...
Three known compounds, stemofoline (1), (2'S)-hydroxystemofoline (2), and (11Z)-1',2'-didehydrostemofoline (3), along with two new alkaloids, stemaphylline (4) and stemaphylline-N-oxide (5), have been isolated from a root extract of Stemona aphylla. The structures of these alkaloids were determined on the basis of their spectroscopic data. The analysis of the crude dichloromethane extract by GC...
گیاهان شورروی با افزودن ترکیبات آلی به خاک و حفاظت خاک در مقابل عوامل فرساینده می‌توانند سبب تغییر ویژگی‌های مختلف خاک و قابلیت استفاده عناصر غذایی خاک گردند. تخریب این اراضی و گیاهان شورروی می‌تواند اثرات نامطلوب زیست‌محیطی به دنبال داشته باشد. جهت بررسی تأثیر وضعیت فیزیوگرافی، نوع گونههای گیاهی و موقعیت رشد گیاه (مستقل یا زیر گونه دیگر) بر ویژگی‌های خاک شوره‌زارها، مطالعه‌ای در منطقه کرسیا، ...
Plants, in arid and semi-arid regions, are leading to form the Nebka geosystem using the decrease of wind speed and the stabilization of quicksand, which they play an important role in desert greening and protection of the environment and natural resources. Therefore, identification of plant species adapted to the environmental conditions in format of Nebka efficiency assessment is very importa...
After the existence of phlebotomine sand flies was first reported in China in 1910, the distribution of different species and their role in the transmission of visceral leishmaniasis (VL) have been extensively studied. Up until 2008, four species have been verified as vectors of VL, namely, Phlebotomus chinensis (Ph. sichuanensis), Ph. longiductus (Ph. chinensis longiductus), Ph. wui (Ph. major...
این مطالعه با هدف بررسی چگونگی اثر سن شتر بلوچی و نوع گونه گیاهی بر ارزش رجحانی گونههای گیاهی مراتع شهرستانزریندشت در جنوب استان فارس انجام شد. جهت اندازهگیری ارزش رجحانی گونههای گیاهی، ابتدا مراتع منطقه تیپبندی و در هر تیپ 10 پلات 2×2 متری در مناطق کلیدی مستقر و گونههای گیاهی شناسایی و پوشش آنها ثبت گردید. سپس ارزش رجحانی گونههای گیاهی به وسیله روش زمانسنجی اندازهگیری شد. جهت بررسی ا...
Background and Objectives: Tamarix dioica is a medicinal herb in Sistan and Baluchestan, which has antidiabetic and antioxidant properties. This research aimed to investigate the effects of the hydro-alcoholic extract of this plant on liver damage caused by a high fat diet. Methods: In this experimental study, 30 males adult Wistar rats, were randomly divided into 3 equal groups. The first g...
A rare moss Buxbaumia aphylla was only recently found in Croatia. Here we report five new localities, one from Dilj Gora and four Mt. Papuk. Small populations on bare acidic soil within the forest along edges were registered.
background & aims of the study: heavy metals contaminate drinking water, air and soils. it is very harmful for humans and other live organisms. phytoremediation is one of the direct bio-remediation methods for heavy metal removal from polluted water and soils. this method is accepted environmentally, economically and aesthetically. the purpose of this study was to assess tamarix hispida capacit...
