Die Möglichkeit einer Differenzierung zwischen dikotylen (Betula vulgaris, Galium aperine, Cirsium arvensis, Stellaria media, Viola arvensis) und monokotylen (Triticum aestivum, Poa annua, Apera spica-venti, Alopecurus myosuroides) Pflanzenarten anhand ihrer LIF-Parameter von der Blattoberund Unterseite wurde geprüft. Diskriminanzanalyse anhand von Fluoreszenzmessungen der Blattoberseite ergab ...

Field trials were conducted over a three-year period (2009 to 2011) to evaluate the efficacy of pendimethalin preplant-incorporated (PPI), bentazon, fomesafen, bentazon plus fomesafen, or halosulfuron applied postemergence (POST) and the sequential application of pendimethalin applied PPI followed by bentazon, fomesafen, bentazon plus fomesafen or halosulfuron applied POST in white bean in Onta...

Naturforsch. 50c, 15-20 (1995); received September 19, 1994 Brassica spp., Sinapis arvensis, Leptosphaeria maculans, Resistance, Indole Phytoalexins Brassica juncea, Brassica carinata and Sinapis arvensis resistant lines to Leptosphaeria maculans and four ...

Agaricus arvensis, a newly isolated basidiomycetous fungus, was found to secrete efficient cellulases. The strain produced the highest endoglucanase (EG), cellobiohydrolase (CBH) and beta-glucosidase (BGL) activities of 0.3, 3.2 and 8U/mg-protein, respectively, with rice straw as the carbon source. Saccharification of the woody biomass with A. arvensis cellulase as the enzyme source released a ...

Intergeneric hybridization was performed between Moricandia arvensis and four inbred lines of Brassica rapa following embryo rescue. Three F(1) hybrid plants were developed from three cross combinations of M. arvensis × B. rapa, and amphidiploids were synthesized by colchicine treatment. Six BC(1) plants were generated from a single cross combination of amphidipolid × B. rapa 'Ko1-303' through ...

Context: The application of encapsulated shoot tips and nodal segments may contribute to the protection of rare and threatened medicinal plants. Although the artificial seed technique has been reported for more than two decades, for medicinal plants this method has not been developed sufficiently. The main limitations in conventional propagation of some species with medicinal value are: reduced...

A global revision of Convolvulus L. is presented, Calystegia R.Br. being excluded on pragmatic grounds. One hundred and ninety species are recognised with the greatest diversity in the Irano-Turanian region. All recognised species are described and the majority are illustrated. Distribution details, keys to species identification and taxonomic notes are provided. Four new species, Convolvulusau...

Aims : The Vinschgau is the driest inner-alpine valley in Eastern Alps and harbours a unique steppe vegetation. We studied these dry grassland communities aimed to answer following questions: Which plant can be found currently? Do syntaxa described by Braun-Blanquet 1960s still prevail area? Has there been any change species composition over last 40–50 years? Study area Along an approximately 4...
