As common ragweed (Ambrosia artemisiifolia L.) is becoming both a health and an economic threat. A greenhouse pot experiment was conducted determining the effects of various nitrogen levels ,soil moisture level and competition levels on the growth parameters of ragweed. Ragweed is a poor competitor when there is high resource availability; however, under disturbance and in the shortage of nutrients and water conditions, the intensity of competition decreases and the ragweed performance is minimally affected. The addition of medium levels of nitrogen to promote the growth of competitive species, prevention of disturbance and establishment of plant communities with stress-tolerant species are measures that should help to prevent the further spread of ragweed.

V pilotnem merilu smo preizkusili novo metdo za remediacijo vrtnih tal z visoko vsebnostjo finih delcev kot neobnovljivega naravnega vira. Dosegli smo visoko učinkovito odstranjevanja Pb Zn in Cd ter uvedli separacijo trdne frakcije tal od procesne tekočine ob hratnem izpiranju tal v eni sami stopnji postopka.

The structure of buckwheat seed endosperm cells was revealed by using Scanning Electron Microscopy (SEM). Morphological differences were observed between normal buckwheat starch granules and those from a Low-Amylose Mutant (LAM). Under physical pressure, mutant starch granules are often squashed. Spherical native starches with a granule diameter similar to those of lipid micelles have a potential for use as fat replacers. Starch from buckwheat LAM may find applications in food products

The overexploitation and impairment of our freshwater resources require land management strategies that support the preservation of green and blue water flow and various ecosystem services. Historical landscape analysis and the influential driving factors of landscape development provide an essential basis for tackling current environmental questions in land and water management. Hence, this article investigates the influence of historical land use pattern on the hydrological processes and provision of blue and green water flow and storage for man and ecosystems under current climate conditions. Moreover, we discuss in how far these findings could be used to predict or optimise future land management options or as a reference for future land and water management. We used digitalized historical land use maps from 1787, 1827, 1940 and 1984 and a digital land use map of present situation from 2009 for our study areas, which are two small scale Slovenian catchments (Reka and Dragonja). The integrated river basin model Soil and water assessment tool was used to simulate the land use change effects on blue and green water flow. The results showed for both catchments that the influence of land use change on total and green water quantity would be statistically insignificant but would have considerable effects on the seasonal flows. In the Reka catchment, historical situations indicate effects on spring and summer blue and green water flow due to a decreased percentage of forest and an increased percentage of grassland and vineyards in the past. Results for the Dragonja catchment indicate past shift from arable land use to forest as decrease in summer green water flow and increase in blue water flow. Possible effects are also increased levels of blue water flow and decreased levels of green water flow during the growing period

By way of scientometric tools, we investigated the usage of international scientific indexing terminology for the subject of medicinal plants, in global databases Web of Science, Medline, CAB Abstracts. We found that, in spite of similarities on narrrower terminological levels, this subject expressess surprising differences among databases on broader levels, which prevents a more precise comparison of publication trends. The results are important from the perspective of the correct usage of user interfaces.
