A significant increase in summer temperatures has been observed for the period 1996-2011 in Poznań, Poland. The phenological response of four weed taxa, widely represented by anemophilous species (Artemisia spp., Rumex spp. and Poaceae and Urticaceae species) to this recent climate warming has been analysed in Poznań by examining the variations in the course of airborne pollen seasons. Pollen d...
The Rumex L. (dock) species for many centuries have been used in medical treatment, through their adstringent, spasmolitic or cholagogic action. In the present study, the in vitro screening of cytotoxic activities of ethanol extract from roots, leaves and fruits of six Rumex species: R. acetosa L., R. acetosella L., R. confertus Willd., R. crispus L., R. hydrolapathum Huds. and R. obtusifolius ...
Rumex japonicus Houtt. is traditionally used as a medicinal plant to treat patients suffering from skin disease in Korea. However, the beneficial effect of Rumex japonicus Houtt. on hair growth has not been thoroughly examined. Therefore, the present study aims to investigate the hair growth-promoting effect of Rumex japonicus (RJ) Houtt. root extract using human dermal papilla cells (DPCs), Ha...
1 Competition is widely thought to be responsible for constraining species limits at the favourable ends of freshwater flooding gradients. However, field studies testing this idea rarely consider the role of competition beyond a species’ field distribution limits. 2 To test whether species distributions are, instead, constrained by physiological limits, and only narrowed by biotic interactions,...
Condensed Y chromosomes in Rumex acetosa L. root-tip nuclei were studied using 5-azaC treatment and immunohistochemical detection of methylated histones. Although Y chromosomes were decondensed within root meristem in vivo, they became condensed and heteropycnotic in roots cultured in vitro. 5-azacytidine (5-azaC) treatment of cultured roots caused transitional dispersion of their Y chromosome ...
