  1. 6. Foliar nutrition: targeted fertilization to test herbivore preference

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

    Author : Johan Penner; [2014]
    Keywords : Foliar nutrition; Salix viminalis; Phratora vulgatissima; Fertilization; Feeding trial;

    Abstract : Abstract   The aim of this study was to increase knowledge of how plants as a whole respond to targeted fertilization and to refine the method of foliar nutrition fertilization. The experiment also aimed to test how herbivores respond when presented with a choice between fertilized and unfertilized Salix leaves in a feeding trial experiment. READ MORE

  3. 7. The foliar bacterial endophyte community in native Pinus radiata: a role for protection against fungal disease?

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Arielle Reivant Munters; [2014]
    Keywords : 16S; bacterial endophytes; endophyte; Illumina; conifers; Monterey pine; Pinus raditata;

    Abstract : Pinus radiata is the most planted tree in the southern hemisphere. The planted trees are especially susceptible to pathogens, but even the native population, nowadays limited tomerely five locations, are threatened by diseases caused by arthropods, fungi and dehydration. READ MORE

  4. 8. Kalcium hos äpple : funktion i växten, inverkan på lagringsduglighet samt metoder för att höja kalciuminnehållet

    University essay from SLU/Dept. of Biosystems and Technology (from 130101)

    Author : Niklas Engelbrekt; [2013]
    Keywords : Äpple; kalcium; fruktkvalitet; kalciumgödsling; bladgödsling; efterskördbehandling; lagringsduglighet;

    Abstract : Kalcium står i nära relation med kvaliteten hos frukten inom en rad olika växtslag, däribland äpple. Genom att tillgodose fruktens behov av kalcium så kan kvaliteten höjas vilket resulterar i ett mer lagringsdugligt äpple samt en större andel klass 1 frukt och därmed en högre inkomst. READ MORE

  5. 9. Möjligheter till ökat utnyttjande av fosfor genom grödan med mineralgödselmedel

    University essay from SLU/Dept. of Soil and Environment

    Author : Lisa Ehde; [2010]
    Keywords : fosforeffektivitet; mineralgödsel; fosforutnyttjande; fosforkemi; rotupptag;

    Abstract : The objective of this thesis is to explore opportunities to enhance the phosphorus use efficiencyof inorganic fertilizers in crop production, with techniques available today and in thefuture. Phosphorus is a finite resource of declining quality; therefore a phosphorus use efficiencyin crop production of only 15-30 % is unacceptable. READ MORE

  6. 10. The effect of moisture, litter and stand age on N fixation in the feathermoss, Pleurozium schreberi

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Helena Gustafsson; [2008]
    Keywords : Pleurozium schreberi; Nitrogen fixation; feathermoss; boreal forest; stand age; moisture; litter; cyano bacteria; succession after fire;

    Abstract : The largest known natural input of nitrogen (N) into the boreal forests occurs through biological fixation by cyanobacteria that live in association with the moss Pleurozium schreberi. There is currently limited knowledge about the factors responsible for the variation in N fixation rates, and specifically what factors drive variability between stands. READ MORE
