field experiments were conducted to determine the influence of single and multispecies competition of common cocklebur (xanthium strumarium l.) and jimsonweed (datura stramonium l.) on corn yield and further the competitive abilities of these weeds .common cocklebur and jimsonweed were established at selected densities within 15 cm on either side of the corn row. common cocklebur and jimsonweed...

A spontaneous intoxication in 34 horses after intake of freshly harvested ensiled maize, accidentally contaminated with young Datura stramonium plants was followed. In a 7-day study, the full clinical status was monitored and this included among others the following: body (rectal) temperature, respiratory and heart rates, colour and humidity of visible mucosae, changes in pupil size, appetite, ...

Thorn Apple or Jimson Weed (Datura stramonium) is a tropane alkaloid containing widespread pest plant growing in central Europe. This predominantly occurs millet, buckwheat and maize cultivation. Therefore, sound cleaning of these crops just as pivotal reliable analytics. The millet at laboratory scale with commercial mechanical devices, such sieves, indented separators table sorters without us...

INTRODUCTION The American continent is very rich in psychoactive plants and fungi, and many pre-Columbian Mesoamerican cultures used them for magical, therapeutic and religious purposes. OBJECTIVES The archaeological, ethno-historical and ethnographic evidence of the use of hallucinogenic substances in Mesoamerica is reviewed. RESULTS Hallucinogenic cactus, plants and mushrooms were used to...

BACKGROUND This study aimed to quantify the allelopathic potential of Datura stramonium (Jimson weed). Sorghum halepense (Johnsongrass) tolerance was assessed by germinating, seed and growing seedlings, dosing of photo-synthesis pigments, followed by treatment with D. stramonium extract tropane alkaloids. RESULTS Preliminary chemical analysis of the extracts showed the presence of alkaloids.T...

T-phylloplanin proteins secreted to aerial surfaces of tobacco (Nicotiana tabacum) by short procumbent trichomes inhibit spore germination and blue mold disease caused by the oomycete pathogen Peronospora tabacina. Many other plants were found to contain water-washed leaf surface proteins (phylloplanins), but the functions and properties of these are not known. Here we extend earlier evidence f...

Potatoes and tomatoes, members of the Solanaceae plant family, serve as major, inexpensive low-fat food sources providing for energy, high-quality protein, fiber, vitamins, pigments, as well as other nutrients. These crops also produce biologically active secondary metabolites, which may have both adverse and beneficial effects in the diet. This limited overview, based largely on our studies wi...
