Tropane alkaloids and toxicity of Convolvulus arvensis.
Horses in a few, localized northern Colorado pastures exhibited weight loss and colic. At post mortem, intestinal fibrosis and vascular sclerosis of the small intestine was identified. The pastures where the affected horses grazed were overrun by field bindweed (Convolvulus arvensis). Bindweed from the pasture was found to contain the tropane alkaloids tropine, pseudotropine, and tropinone and ...
متن کاملEect of the pre-emergence bioherbicide Phomopsis convolvulus on seedling and established plant growth of Convolvulus arvensis
The eects of the fungal pathogen Phomopsis convolvulus Ormeno on seedling and established plant performance of Convolvulus arvensis L. were compared under both controlled and ®eld conditions. Under a controlled environment, a granular barley formulation of the fungal inoculum that had been applied on to the soil surface of pots containing pre-germinated C. arvensis seeds resulted in above-grou...
متن کاملAspergillus leaf spot of field bindweed (Convolvulus arvensis L.) caused by Aspergillus niger in China
Leaf spot was found on field bindweed (Convolvulus arvensis L.) in Shihezi City, Xinjiang Province, China, during the summer of 2015. Pathogens were isolated from the infected leaves of field bindweed and identified as Aspergillus niger based on morphological and molecular analyses (internal transcribed spacer rDNA and β-tubulin gene). A pathogenicity test confirmed that Aspergillus niger cause...
متن کاملCharacterizing demographic variation and contributions to population growth rate in a declining population.
1. Understanding how demographic variation translates into variation in population growth rate (λ) is central to understanding population dynamics. Such understanding ideally requires knowledge of the mean, variance and covariance among all demographic rates, allowing the potential and realized contribution of each rate to λ to be estimated. Such studies require integrated monitoring of all dem...
متن کاملThe Effect of Convolvulus arvensis Dried Extract as a Potential Antioxidant in Food Models.
In this study, the antioxidant activity of the Convolvulus arvensis Linn (CA) ethanol extract has been evaluated by different ways. The antioxidant activity of the extract assessed by 2,2'-azino-bis-3-ethylbenzothiazoline-6-sulphonic acid (ABTS) radical cation, the oxygen radical absorbance capacity (ORAC) and the ferric reducing antioxidant power (FRAP) was 1.62 mmol Trolox equivalents (TE)/g ...
