  1. 11. Endophytic growth of Clonostachys rosea in tomato and Arabidopsis

    Master-uppsats, SLU/Dept. of Forest Mycology and Plant Pathology

    Författare :Sofia Alvarez Nordström; [2014]
    Nyckelord :biological control agent; clonostachys rosea; endophytic colonization; induced resistance;

    Sammanfattning : In the future, an increased food demand together with restrictions of pesticide use will require new options of disease management within agriculture. Usage of biological control agents (BCAs) is a feasible alternative. For example, BCAs may reduce pathogen attacks in plants by induced resistance. LÄS MER

  4. 13. The effect of domestication on insect resistance in cotton : bioassays with the insect herbivores Spodoptera littoralis and Agriotes spp.

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

    Författare :Joakim Sjöstrand; [2014]
    Nyckelord :Spodoptera littoralis; Agriotes lineatus; insect resistance; cotton; gossypium;

    Sammanfattning : A plant's defensive ability against herbivore attack can be influenced by many different factors, one of them being domestication. During human selection to improve the yield of plants, the resistance against herbivore attack can have been lowered, due to a trade-off for use of resources between these traits in the plants.

  5. 14. Fritidsodlarens främsta försvar : trädgårdsväxter som skydd mot skadedjur

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

    Författare :Anna Danielsson; [2014]
    Nyckelord :nyttodjur; skadedjur; attrahera; repellera; trädgårdsväxter; odlingsmiljö; fritidsodling; gröngödsling; companion plants; biological control;

    Sammanfattning : Fritidsodling är ett stort intresse i Sverige och det odlas trädgårdsväxter både för prydnad och för konsumering. Det finns ett stort antal skadedjur som kan förstöra växterna och reducera skörd. Denna litteraturstudie undersöker om det finns trädgårdsväxter som kan påverka skadedjuren negativt. LÄS MER

  7. 15. Effects of leaf beetle herbivory on pollination success and fruit development in woodland strawberry Fragaria vesca

    Master-uppsats, SLU/Dept. of Ecology

    Författare :Lisa Malm; [2013]
    Nyckelord :herbivory; pollination success; pollinator reference; fruit development; fruit yield; leaf beetles; Galerucella tenella; Galerucella sagittariae; Fragaria vesca;

    Sammanfattning : Cultivating well-developed and marketable garden strawberries (Fragria x ananassa) and woodland strawberries (Fragaria vesca) depends on successful pollination by insects. Organic garden strawberry plantations harbour higher pollinator densities and have been shown to produce bigger and better developed fruits than conventional farms. LÄS MER
