Arable-weed flora and its pollen representation: A case study from the eastern part of France
2007
International audience; Local pollen deposition in human-influenced vegetation types is studied with the aim of establishing the relationship between arable-weed vegetation and its pollen representation as an aid in interpreting human presence and impact on vegetation from pollen assemblages. The study area is located in the Franche-Comté region, eastern part of France. The presence of plants within 100 m2 plots and their pollen representation in moss samples within the same plots was recorded from different crops and annual fallows. Patterns in the vegetation and pollen assemblages were investigated separately using principal coordinate analysis (PCoA). Procrustean co-inertia analysis (PCI…
Copper binding capacity of root exudates of cultivated plants and associated weeds
2001
International audience; Cu binding to root exudates of two cultivated plants, wheat (Triticum aestivum) and rape (Brassica napus), and two weeds associated with wheat, dog daisy (Matricaria inodora) and cornflower (Centaurea cyanus), was studied in vitro under hydroponic and sterile conditions. Nutrient solutions were prepared with or without P. A MetPLATE microbiological test was used to assess the metal complexing capacity of root exudates. In the P-deficient solutions, no exudation was observed for any of the four plants; consequently, no Cu binding occurred. When P was present in the nutrient solutions, the plant exudates displayed differing abilities to complex Cu. No difference was de…
Atlas of the Baltic languages: plant names of Slavonic origin
2015
Atlas of the Baltic Languages: Plant Names of Slavonic Origin The article investigates Slavonic-derived plant names in dialects of the two surviving Baltic languages – Latvian and Lithuanian. Historically, these Slavonisms were originally adopted by small-scale regional dialects, which are now disappearing. In 2009, a pilot study for the Atlas of the Baltic Languages was published. It comprised 12 geo-linguistic maps with Latvian, Lithuanian and English commentaries. 2012 saw the publication, in CD format, of the Atlas ’s first volume: Lexis 1: Flora . The material analysed concerns names for: (1) wild plants, e.g., cornflower, nettle, waybread, milfoil, dandelion, plantain; (2) cultivated …
