  1. 21. Biological control of powdery mildew in greenhouse produced cucumber : an evaluation of two microbiological control agents

    University essay from SLU/Dept. of Plant Breeding (from 130101)

    Author : Anna-Carin Almqvist; [2013]
    Keywords : powdery mildew; cucumber; Golovinomyces cichoracearum; Podosphaera xanthii; biological control; Ampelomyces quisqualis; Pythium oligandrum;

    Abstract : Powdery mildew is a serious problem in both field and greenhouse cucumber production and can cause serious infection and radically reduced yields. Today, powdery mildew is the main disease in greenhouse produced cucumber. Disease control should preferably be both efficient and environmentally friendly, which is not easy to achieve at all times.

  3. 22. Role of WRKY20 transcription factor and raffinose in plant defense responses upon Bacillus amyloliquefaciens strain 5113-mediated priming in Arabidopsis thaliana

    University essay from SLU/Dept. of Plant Biology and Forest Genetics (until 131231)

    Author : Jonas Kjellin; [2012]
    Keywords : Priming; Bacillus amyloliquefaciens; WRKY20; raffinose; salicylic acid; jasmonic acid; isoamylase;

    Abstract : Biocontrol through beneficial bacteria-mediated priming can promote plant growth and increase resistance to biotic and abiotic stress. Bacillus amyloliquefaciens strain 5113 has been identified as a promising candidate for priming by increasing stress resistance and promoting growth in oil seed rape (Brassica napus). READ MORE

  4. 23. The effect of combining two biological control microbes on seed and root colonization

    University essay from SLU/Dept. of Forest Mycology and Plant Pathology

    Author : Jinhui Wang; [2012]
    Keywords : Biological control; Root Colonization; Clonostachys rosea; Pseudomonas chlororaphis;

    Abstract : Clonostachys rosea strain IK726 and Pseudomonas chlororaphis strain MA342 are two promising biocontrol microbes which both has various biocontrol mechanisms to control many seed and soil-borne plant diseases. Because a potential additive effect may exist between these two biocontrol microbes, like an expanded antagonistic spectrum and enhanced persistence of biocontrol effect, we expected to get a more competitive biocontrol with a mixture of IK726 and MA342.

  5. 24. The influence of plant sex on the performance of a detrimental herbivore and two biocontrol agents in the dioecious grey willow, Salix cinerea

    University essay from SLU/Dept. of Ecology

    Author : Md. Faisal Kabir; [2012]
    Keywords : plant sex; Salix; herbivore; omnivore; biocontrol; dioecious; Phratora vulgatissima; Anthocoris nemorum; Orthotylus marginalis;

    Abstract : Dioecious plants can be used as model systems for studying how variation in host plants affects plant-insect interactions. This thesis describes investigations into the impact of plant sex on plant-herbivore-predator interactions for the host plant Salix cinerea. READ MORE

  6. 25. Biotic priming of growth and stress tolerance in cereals

    University essay from SLU/Dept. of Plant Biology and Forest Genetics (until 131231)

    Author : Martin Palmqvist; [2012]
    Keywords : Biocontrol; crop plant; priming; stress tolerance; wheat; nano material; Bacillus amyloliquefaciens;

    Abstract : Instead of using chemical pesticides for plant protection there is the possibility to activate plants´ innate immunity defense against pests and diseases using bacteria. Many bacteria have been tested for their priming potential while not much research has assessed the priming effect against abiotic stress factors. READ MORE
