The aim of the present study was to analyse the Rumex pollen season dynamics in Lublin in 2001-2010 and to find relationships between season parameters and meteorological conditions. This study was carried out by the volumetric method using a Lanzoni VPPS 2000 trap. The start and end dates of each season were determined based on the 98% method. The effects of meteorological factors on the Rumex pollen seasons were analysed by employing Spearman’s correlation test. On average, the sorrel pollen season started on 13 May (±7 days), ended on 7 September (±6 days), and lasted nearly four months (±9 days). The highest pollen concentrations were recorded in June and July. A significantly negative correlation was found between season duration and Seasonal Pollen Index (SPI). During shorter pollen seasons, higher pollen counts were recorded. In all study years, the seasons were right-skewed. The pollen concentration was most strongly correlated with humidity and mean air temperature. The season parameters (onset, end, peak date, peak value, SPI value) were primarily dependent on air temperature before and during the pollen season.

Sex-ratio bias in seeds of dioecious Rumex species with sex chromosomes is an interesting and still unsettled issue. To resolve gender among seeds of R. acetosa and R. thyrsiflorus (two species with an XX/XY1Y2 sex chromosome system), this work applied a PCR-based method involving DNA markers located on Y chromosomes. Both species showed female-biased primary sex ratios, with female bias greater in R. acetosa than in R. thyrsiflorus. The observed predominance of female seeds is consistent with the view that the female biased sex ratios in Rumex are conditioned not only postzygotically but also prezygotically

We used the DPPH method to assess in vitro the antiradical activity of extracts from the roots, leaves and fruits of six Rumex L. (dock) species. Data from preliminary screening indicated that all the tested extracts showed antioxidant properties. The degree of antiradical activity depended upon the plant part. Fruit extracts from R. hydrolapathum Huds., R. obtusifolius L. and R. confertus Willd. showed stronger antiradical properties than the other tested material. We also determined tannin content levels in the extracts and their correlation with antioxidant activity.

Eight anthracene derivatives (chrysophanol, physcion, emodin, aloe-emodin, rhein, barbaloin, sennoside A and sennoside B) were signified in six species of Rumex L. genus: R. acetosa L., R. acetosella L., R. confertus Willd., R. crispus L., R. hydrolapathum Huds. and R. obtusifolius L. For the investigations methanolic extracts were prepared from the roots, leaves and fruits of these species. Reverse Phase High Performance Liquid Chromatography was applied for separation, identification and quantitative determination of anthracene derivatives. The identity of these compounds was further confirmed with UV-VIS. Received data were compared. The roots are the best organs for the accumulation of anthraquinones. The total amount of the detected compounds was the largest in the roots of R. confertus (163.42 mg/g), smaller in roots R. crispus (25.22 mg/g) and the smallest in roots of R. hydrolapathum (1.02 mg/g).

Przebadano pięć gatunków szczawiu (Rumex alpinus, R. crispus, R. hydrolapathum. R. obtusifolius, R. patientia) dostarczających surowca określanego wspólną nazwą korzeń kobylaka - Radix Lapathi (syn. Rx Hydrolapathi). Analizą objęto badania ilościowe garbników i antra- związków (glikozydy i wolne aglikony). W badaniach jakościowych wykorzystano chromatografię cienkowarstwową.
