  1. 1. Rhizobacteria associated to Vitis vinifera and their effect on the control of Xiphinema index, Meloidogyne ethiopica and Vitis growth

    Detta är en avhandling från ; Dept. of Crop Production Ecology, Swedish University of Agricultural Sciences

    Författare :Erwin Aballay; Sveriges lantbruksuniversitet.; [2012]
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Plant-parasitic nematodes are one of the most important pests affecting the growth of vineyards due to the destruction of new roots. Several species are associated with this problem, the most important being the ectoparasite Xiphinema index and the endoparasite Meloidogyne ethiopica. LÄS MER

  2. 2. Use of rhizobacteria for the alleviation of plant stress

    Detta är en avhandling från ; Department of Forest Mycology and Plant Pathology, Swedish University of Agricultural Sciences

    Författare :Islam Ahmed Moustafa Abd El-Daim; Sveriges lantbruksuniversitet.; [2015]
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Plant growth promoting rhizobacteria are beneficial microbes able to induce plant stress tolerance and antagonise plant pathogens. The present study showed that wheat seedlings pre-treated with Bacillus thuringiensis AZP2 had better tolerance to severe drought stress and showed 78% greater plant biomass and five-fold higher survivorship compared to wheat seedlings not treated with the bacterium.

  3. 3. Reproductive biotechnologies in Swedish male alpacas

    Detta är en avhandling från ; Department of Clinical Sciences, Swedish University of Agricultural Sciences

    Författare :Maria Celina Abraham; Sveriges lantbruksuniversitet.; [2016]
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Alpacas have become more popular during the last decades. The herds have been built up by importing live animals since reproductive biotechnologies, for example artificial insemination and semen preservation, are not well-developed in this species. LÄS MER

  4. 4. Patterning during embryo development in Pinus : with special emphasis on somatic embryogenesis in Scots pine (Pinus sylvestris L.)

    Detta är en avhandling från ; Department of Plant Biology, Swedish University of Agricultural Sciences

    Författare :Malin Abrahamsson; Sveriges lantbruksuniversitet.; [2016]
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Somatic embryogenesis is an attractive method to propagate conifers vegetatively. However, many species belonging to Pinus are recalcitrant to somatic embryo development. The overall aim of this thesis has been to gain a better understanding of the developmental pathway leading to cotyledonary somatic embryos of Scots pine (Pinus sylvestris). LÄS MER
