The weed seed bank of a long-term tillage study in subarctic Alaska was studied at the end of 10 years of continuous spring barley (Hordeum vulgare L.). Tillage treatments were: no-till, disked once (spring), disked twice (spring and fall), and chisel plow (fall). Soil cores were obtained from each tillage treatment and seeds were manually separated from soil after washing through sieves. Tilla...

Evidence suggests that belowground self-recognition in clonal plants can be disrupted between sister ramets by the loss of connections or long distances within a genet. However, these results may be confounded by severing connections between ramets in the setups. Using Potentilla reptans, we examined severance effects in a setup that grew ramet pairs with connections either intact or severed. W...

Lundberg, M., 2011. Systematics and polyploid evolution in Potentilleae (Rosaceae). This thesis comprises studies of the phylogenetic relationships in the flowering plant clade Potentilleae in Rosaceae. The relationships were elucidated by using DNA sequence data from the nuclear genome as well as from the plastid genome. In particular, the focus of the studies was the investigation of allopoly...

Potentilla fulgens L., a locally used medicinal plant with reported hypoglycemic, antihyperglycemic, and anti-tumor properties was studied. The polar extracts of P. fulgens L. were assessed and found to induce cytotoxic response at different concentrations against a panel of human carcinoma cells such as THP-1 leukemia, HEP-2 liver, OVCAR-5 ovary, A-549 lung, PC-3 prostrate, and SF-295 neurobla...

This paper presents the results of research on Ba, Li and Ti content in six species herbs sampled from mid-field wet depressions soil. These temporary flooded were surrounded by arable crops, permanent grassland shrubby vegetation. The area was located eastern part Mazovian Voivodeship, east-central Poland. following plants used experiment: corn mint (Mentha arvensis L.), purple marshlocks (Com...
