Rumex thyrsiflorus Fingerh. is one of the few dioecious plant species, which have sex chromosomes. We conducted the preliminary experiments to determine the type of morphogenesis of R. thyrsiflorus explants cultured in vitro and to verify, using PCR-based methods, if there is the relationship between sex and morphogenetic response of explants micropropagated under in vitro conditions. The resul...

Earlier work on the submergence-tolerant species Rumex palustris revealed that leaf anatomical and morphological changes induced by submergence enhance underwater gas exchange considerably. Here, the hypothesis is tested that these plastic responses are typical properties of submergence-tolerant species. Submergence-induced plasticity in leaf mass area (LMA) and leaf, cell wall and cuticle thic...

A model is presented of the regulation of ethylene biosynthesis in relation to submergence and flooding resistance. It is based on time-course measurements of ethylene production, ethylene accumulation, and concentrations of free and conjugated 1-aminocyclo-propane-1-carboxylic acid (ACC) in submerged and drained flooding-resistant Rumex palustris Sm. and flooding-sensitive Rumex acetosella L. ...

BACKGROUND Very few ethnoveterinary surveys have been conducted in central Europe. However, traditional knowledge on the use of medicinal plants might be an option for future concepts in treatment of livestock diseases. Therefore the aim of this study was to document and analyse the traditional knowledge and use of homemade herbal remedies for livestock by farmers in four Swiss cantons. METHO...

this study investigated the effect of rumex sc (commercial product which includes of saccharomyces cervisiae, saponin and essential oils) on rumen fermentation, blood glucose, urea, milk yield and milk composition. animals were offered a basal diet containing alfalfa hay (15.5%), corn silage (24%), beet pulp (7%) and concentrate (53.5%). additionally, rumex sc was included in the experimental d...
