Organic dairy farmers often introduce alternative pasture species, such as chicory (Cichorium intybus) and narrow-leaved plantain (Plantago lanceolata), to their swards because of their higher mineral contents, yet they are concerned about the presence of weed species such as docks (Rumex spp.) and dandelion (Taraxacum officinale). The mineral content and nutritive value of both desired and les...
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. ...
