Seed germination generally presents a peak in the next growing season after a fire. Among other factors associated with fire are the increase of soil nitrogen and changes in the pH of the soil. In this study, we addressed the question, whether or not the germination response of eight species is linked with the increase in pH and nitrogenous compounds in the germination media? We assessed the se...

The first study of the aphid fauna from Chukotka Autonomous Okrug has been made; 18 species are reported from this territory, the most north-eastern of Russia and of the Palaeartic Region. Five new species are described: Aphis aquilonalis sp. nov. on Rumex arcticus Trautv.; Aphis beringiensis sp. nov. were collected by yellow trap; Macrosiphoniella (Asterobium) jaroslavi sp. nov. on Artemisia a...

Promotion of germination by red light fails after prolonged dark imbibition of Rumex crispus L. seeds, indicative of a secondary dormancy. The degree and rate of inception of the dormancy increases with increasing temperature. Following establishment of the dormancy, germination response to red light can be restored by either prolonged cold treatment or brief high temperature shifts. Loss of ph...

Two new naphthalene acylglucosides, rumexneposides A (1) and B (2), together with 12 known compounds (3-14), were isolated from the roots of Rumex nepalensis. Their structures were established by chemical and spectroscopic methods. The biological activities of compounds 1-14 as well as an additional 11 compounds previously isolated from R. nepalensis and Rumex hastatus (15–25) were evaluated ag...

PREMISE OF THE STUDY Nuclear microsatellite markers were developed in Rumex bucephalophorus subsp. canariensis (Polygonaceae) to investigate its genetic diversity and structure. METHODS AND RESULTS Sixteen polymorphic microsatellite markers were obtained using 454 next-generation sequencing with di-, tri-, and tetranucleotide repeats. The average number of alleles was 5.688 and 3.813 for R. b...

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...
