Restoring habitats degraded by intensive agriculture is challenging, and the resulting communities often have lower quality host fewer species than reference ecosystems. To improve restoration outputs, we need to understand what limits both establishment performance of target in restored populations. In this study, focused on grassland with regional seeds compared two herbs, Betonica officinali...

The aerial parts of Centaurea deusta Ten. afforded in addition to several known compounds, mainly sesquiterpene lactones, one new eudesmanolide and one new elemane derivative. Structures of the new compounds were elucidated by spectroscopic methods. The in vitro antifungal and antibacterial activities of the isolated compounds was tested, using the microdilution method. All compounds tested sho...

A number of studies have suggested a link between hybridization and invasion. In this study, we experimentally test the potential for hybridization to influence invasion through a greenhouse common garden study. Diffuse knapweed (DK) (Centaurea diffusa Lam.) was introduced to North America with admixture from spotted knapweed (SK) (Centaurea stoebe subsp. stoebe L.). Comparisons between North A...

The content of biologically active substances and antioxidant activity in leaves inflorescences three species from the tribe Cynareae Asteraceae family: Centaurea cyanus,Centaurea macrocephala, Rhaponticum carthamoides, grown under conditions Central Siberian Botanical Garden introduction was studied. It determined that contain flavonols, catechins, tannins, carotenoids, pectin substances. high...
