  4. 2. Organic acids in root exudates and soil solutions. Importance to calcicole and calcifuge behaviour of plants

    Author : Lena Ström; Institutionen för naturgeografi och ekosystemvetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; nutrient-solubilisation; iron; phosphate; nutrient-limitations; citrate; oxalate; organic acids; root exudation; acidifuge; Calcicole; calcifuge; adaptations.; Plant ecology; Växtekologi;

    Abstract : Many vascular plant species are unable to colonise calcareous sites, the floristic composition of adjacent limestone and acid silicate soils differing markedly. The inability of these 'calcifuge' species to establish themselves and grow on limestone soil appears to mainly be related to their low capacity for solubilising and absorbing phosphate and/or iron from such soils.

  7. 5. Capillary zone electrophoresis for the analysis of low molecular weight organic acids in environmental systems

    Author : Jessika Hagberg; Bert Allard; Stefan Karlsson; Anders Düker; Patrick van Hees; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; capillary zone electrophoresis; capillary zone electrophoresis-electrospray ionization-mass spectrometry; low molecular weight organic acids; pKa; Chemistry; Kemi; Kemi; Chemistry;

    Abstract : Capillary zone electrophoretic (CZE) methods were developed to identify and quantify low molecular weight (LMW) organic acids in environmental samples. Sensitivity and selectivity were optimised by adapting the background electrolyte to the characteristics of analytes, and by using different modes of detection and injection. READ MORE
