The inhibitory effect of galloyl pedunculagin (GP) isolated from Platycarya strobilacea on the activity and autophosphorylation of Ca(2+)- and phospholipid-dependent protein kinase (C-kinase) was examined in vitro. It was found that (i). GP inhibited the activity (phosphorylation of complement C3 from guinea pig) of C-kinase alpha (rat brain) in a dose-dependent manner with an ID(50) of approx....
Changes in slope aspect have important effects on the C, N and P nutrient contents stoichiometric characteristics of plants soils. As an forest type subtropical region, Pinus massoniana forests play role restoration development ecosystems. In this study, effect stoichiometry leaves soils four P. types (i.e., pure (PF), massoniana-Liquidambar formosana mixed (PLM), - Platycarya strobilacea (PPM)...
the purpose of this study was to evaluate the species-environment relationships in arid and semi-arid rangelandsof nodushan, yazd. the plant species cover and the environmental variables were measured at 9 sites. soil sampleswere taken for measurement of 12 attributes in 0-10 cm and 10-80 cm layers. vegetation was classified using twowayindicator species analysis (twinspan). data was analyzed u...

Background and objectives: The genus Ephedra (Ephedraceae) consists of about 40 species of mostly shrubs and rarely small trees around the world. In the present study, the essential oil (EO) diversity and genetic relationships were investigated in six Ephedra species from Iran using Random Amplified Polymorphic DNA (RAPD) markers. Methods: The plants were collected from two different provinces;...
جنس افدرا از لحاظ خصوصیات گیاهشناسی، به راسته کلامیدوسپرم، خانواده افدراسه تعلق دارد. افدرا بصورت درختچه ای همیشه سبز و شاخه های آن فاقد برگ می باشد. ساقه های آنها، افراشته یا خمیده است. گل ها دو پایه و مخروطی شکل، میوه های کروی به رنگ قرمز و گهگاه زرد رنگ است. افدرا منبعی از 2 آلکالوئید با ارزش شامل افدرین و سودوافدرین است. ساقه های خشک شده گونه های افدرا موجب برطرف کردن سرماخوردگی، آنفولانزا،...
When measuring plant functional traits across geomorphologies, 5–10 healthy individuals of a species are commonly sampled. However, whether more should be sampled in habitat-heterogeneous karst vegetation remains unknown. In this study, two dominant tree ( Clausena dunniana and Platycarya strobilacea ) evergreen broadleaved mixed forests Southwestern China were selected. On the basis large quan...
