  1. 1. Spray Induced Gene Silencing in Phytophthora infestans : investigating exogenous dsRNA application for the control of potato late blight

    Master-uppsats, SLU/Dept. of Plant Breeding (from 130101)

    Författare :Poorva Sundararajan; [2024]
    Nyckelord :Phytophthora infestans; RNAi; potato late blight; gene silencing; SIGS;

    Sammanfattning : Phytophthora infestans is an oomycete pathogen and the causal agent of late blight disease in potato and tomato. Even today, it causes massive loss to crop and economy worldwide. Current disease control strategies include breeding for resistance and extensive fungicide spray. LÄS MER

  3. 2. Promoting lateral bud growth in sweet potato (Ipomoea batatas) : comparing the foliar application of synthetic phytohormone and coconut water

    Kandidat-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)

    Författare :Johan Valeur; [2020]
    Nyckelord :sweet potato; Ipomea batatas; apical dominance; phytohormones; coconut water; foliar application; biostimulant; vegetative propagation;

    Sammanfattning : Sweet potato (Ipomea batatas) is an important crop grown worldwide with a rising interest in production in Europe and Sweden. Swedish producers are looking for ways to grow the crop but are facing problems because of low-quality slips from import which leads to a non-profitable production. LÄS MER

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

    Kandidat-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)

    Författare :Niklas Engelbrekt; [2013]
    Nyckelord :Äpple; kalcium; fruktkvalitet; kalciumgödsling; bladgödsling; efterskördbehandling; lagringsduglighet;

    Sammanfattning : 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. LÄS MER

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

    Kandidat-uppsats, SLU/Dept. of Soil and Environment

    Författare :Lisa Ehde; [2010]
    Nyckelord :fosforeffektivitet; mineralgödsel; fosforutnyttjande; fosforkemi; rotupptag;

    Sammanfattning : 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. LÄS MER

  7. 5. Potato yield and tuber set as affected by phosphorus fertilization

    L3-uppsats, SLU/Horticulture

    Författare :Joakim Ekelöf; [2007]
    Nyckelord :fertilizer; irrigation; phosphorus; phosphate; foliar; application;

    Sammanfattning : In order to minimize phosphorus (P) leaching from potato cropping systems, P recommendations based on facts regarding the influence on the potato plant is needed. A literature study and a practical experiment were conducted in order to determine potato yield and tuber set as affected by Pfertilization. LÄS MER
