  1. 1. Blåklint : ett ökande problem i svensk växtodling

    University essay from SLU/Dept. of Crop Production Ecology

    Author : Johan Johnsson; [2021]
    Keywords : bekämpning; biologi; blåklint; Centaurea cyanus L; herbicider; intervjuer; konkurrensstarka grödor; rådgivare; seriesammanställning; växtföljd;

    Abstract : Blåklint (Centaurea cyanus L) är ett vinterannuellt örtogräs som kan orsaka kraftiga skördesänkningar i odlade grödor. Den är idag ett ökande problem i svensk växtodling eftersom höstsådda grödor odlas i stor utsträckning. READ MORE

  3. 2. Flower preferences among weed-visiting insects in field edges

    University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

    Author : Isolde Galin; [2021]
    Keywords : arable field; flower preference; pollinator; weeds;

    Abstract : The increased improvement of weed control throughout the years has led to a decrease in the amount of weed in arable fields. Weeds can be a source of pollen and nectar. Pollinating insects are dependent on a variety of plants for nectar and pollen. READ MORE

    Keywords : Plant; Competition; Plant soil feedback; Yarrow; Achillea millefolium; Centaurea cyanus; Soil; pH; Nitrate; Ammonium; Nitrogen; Soil texture; Light; Sweden; Height; Biomass; Field; Growth chamber; Greenhouse; Ecology; Relative fitness; Stabilizing niche; Konkurrens; Jordmån; Kärlväxter; Röllika; Blåklint;

    Abstract : Competition between plant individuals and how plants alter soil properties are key processes which drive changes in plant communities over time. Estimating the relative importance of these processes and how they affect plant growth in different ecological contexts and communities is an active area of research. READ MORE

  5. 4. Examining the competitive abilities of cornflower (Centaurea cyanus) in a growth chamber experiment.

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Emil Karlsson; [2019]
    Keywords : Centaurea cyanus; Papaver rhoeas; Avena sativa; Cornflower; Growth chamber; Plant competition; Plant ecology; LAI; Root biomass; Root length; Biomass; Dry weight; Interspecific competition; Blåklint; Kärlväxter; Konkurrensförmåga; Ekologi;

    Abstract : Competition between different species (interspecific competition) is an important factor to consider when estimating population trends, geographic distributions, and management options of species. Many historically common vascular plant species found in agricultural environments have been negatively affected by changes in community composition and in turn, changes in competition pressures.

  6. 5. Känsligheten hos blåklint mot en ALS-inhibitor

    University essay from SLU/Dept. of Crop Production Ecology

    Author : Ida Gustafsson; [2014]
    Keywords : ALS-inhibitor; blåklint; Centaurea cyanus L.; herbicidresistens;

    Abstract : Växtföljder fick mindre betydelse för den sanerande effekten på ogräs när de kemiska bekämpningsmedlen introducerades på 1940-50-talen. Fram till sommaren 2010 hade herbicidresistens upptäckts i 194 arter i över 340 000 olika fält världen över och det är ett problem som kommer att öka i världen. READ MORE
