Photosynthesis, Growth, Carbon Allocation, and Fruit Load of Frangula caroliniana and Rhamnus cathartica
Rhamnus cathartica is an invasive shrub capable of high fecundity in North America. The physiology of R. cathartica has received little attention, but more is needed to understand traits that enhance its success in disturbed environments. Such data may help to predict invasiveness of closely related species such as Frangula caroliniana. We hypothesized that R. catharticawould have greater relat...
متن کاملAbove- and Belowground Impacts of European Buckthorn (Rhamnus cathartica) on Four Native Forbs
Fast-growing European buckthorn (Rhamnus cathartica) shrubs are aggressively invading woodlands in eastern and midwestern North America. Buckthorn casts dense shade, alters soil conditions, and may be allelopathic. We used greenhouse and field experiments to investigate aboveand belowground effects of Rhamnus on four herbaceous species native to southern Wisconsin. In the greenhouse, we assesse...
متن کاملDevelopment of soybean aphid (Homoptera: Aphididae) on its primary overwintering host, Rhamnus cathartica.
Thermally dependent development of soybean aphid (Aphis glycines Matsumura) and common buckthorn (Rhamnus cathartica L.) were examined in growth chambers in spring 2005. Models based on ambient air temperatures for all development events were developed. Adjusted models were developed to account for heat units acquired because of solar radiation. These models were tested at field sites in Guelph...

Rhamnus L. is the genus of Rhamnaceae in Iran with nearly eight species. These species are used as valuable shrubs. This research was carried out in order to investigate the anatomical leaf. Samples from nine populations of Rhamnus pallasii and Rhamnus cathartica were taken. Treatment specimen cover various habitats from north of Iran, moreover herbarium samples were taken into account. The res...
