Beetle grazing reduces natural infection of Rumex obtusifolius by fungal pathogens

A New Anthraquinone Isolated from Rumex Obtusifolius

In this research we studied Rumex obtusifolius (Polygonaceae) along with other plants used in traditional medicine in relation to the chemical reaction FBIT (Ferriprotoporphyrine Biocrystallization Inhibition Test) which may provide information on a possible action mechanism for presumed antimalarial plants. According to folk medicine Rumex obtusifolius has a pronounced detoxifying effect on th...

Nutritive Value and Digestibility of Rumex obtusifolius in Three Phenological Stages by Chemical, Nylon Bag and Gas Production Methods

The present study was conducted to identify nutritional value of Rumex obtusifolius in three phenological stages (vegetative growth, flowering, and maturity). Samples were randomly taken in pastures of Saravan in Rasht, Iran in 2015. After drying and grinding, the chemical compositions of Crude Protein (CP), Crude Fiber (CF), Ether Extract (EE), Total Ash (ASH), Neutral Detergent Fiber (NDF), a...

Studies of the Amino Acid Sequence of Plastocyanin from Rumex obtusifolius (Broad-Leaved Dock)

Plastocyanins are low-molecular-weight cuproproteins, which occur in the chloroplasts of plants and algae. The exact biological function of the protein remains uncertain, but is probably associated with photosynthetic electron transport (Gregory, 1971). The small size and blue colour of the protein simplify the purification of plastocyanin, and studies with a number of species have been reporte...

Competitive advantage of Rumex obtusifolius L. might increase in intensively managed temperate grasslands under drier climate

Allelopathic effects of Rumex obtusifolius leaf extracts against native grassland species

In perennial grasslands R. obtusifolius (broad-leaved dock) is often surrounded by certain plant species. Thus, it is hypothesized for the current study that Rumex can affect their neighbouring plant species by allelopathic interactions. To test this hypothesis, in a series of laboratory and field experiments aqueous extracts of green R. obtusifolius leaves were sprayed on seeds of 14 herbaceou...
