  1. 1. Screening of early root growth characteristics in seedlings of Nordic spring barley : utilization of hydroponics and GWAS for identification of QTLs and candidate genes for root traits

    University essay from SLU/Dept. Of Plant Breeding

    Author : Karl-Johan Fabo; [2021]
    Keywords : spring barley; plant breeding; root growth; early vigor; seminor roots; GWAS; QTL; quantitative traits; quantitative genetics; marker-assisted breeding; hydroponics;

    Abstract : In the Nordic countries, the cultivation of barley (Hordeum vulgare L.) has a long history, and as one of the major cereals in the world, barley is of global importance for food security. The world population is growing, which naturally will increase demands for agricultural outputs. READ MORE

  3. 2. Analysis of chlorophyll synthesis mutants xantha-m and xantha-j of Hordeum vulgare L.

    University essay from Lunds universitet/Examensarbeten i molekylärbiologi

    Author : Fredrik Klinghammer; [2020]
    Keywords : Biology and Life Sciences;

    Abstract : The xantha phenotype of barley is observable as a yellow plant and caused by an inability to correctly synthesize chlorophyll. Chlorophyll is a tetrapyrrolic pigment containing magnesium, and is integral for photosynthesis in plants. READ MORE

  4. 3. Is it possible to find a method that shows a correspondence between a known mutation and the phenotype in barley wax less mutants?

    University essay from Lunds universitet/Examensarbeten i molekylärbiologi

    Author : Lovisa Kjellén; [2016]
    Keywords : Biology and Life Sciences;

    Abstract : The wax on the stem and leafs of the barley (Hordeum vulgare L.) plant has a protective function and is produced by the cells on the plant's outer surfaces. There are several available barley mutants where the wax production has been stopped. Four mutants are the single-site mutants cer-c. READ MORE

  5. 4. The origin of naked barley (Hordeum vulgare L. ssp. vulgare) studied bythe nud gene

    University essay from Molekylär genetik; Tekniska högskolan

    Author : Dan Gustafsson; [2013]
    Keywords : Accessions; barley landraces; domestication; ethylene response factor; monophyletic origin; nud gene.;

    Abstract : The exact origin of the peculiar naked barley is somewhat illusive. There   is a debate whether it has a single, monophyletic origin or a multiple, paraphyletic origin. It is from previous Asian studies on naked   barley known that a mutation   or a deletion of the nud gene expresses the   naked seed phenotype. READ MORE

  6. 5. Responses of aphids to semiochemicals released from ladybirds

    University essay from SLU/Dept. of Ecology

    Author : Feng Youren; [2012]
    Keywords : Rhopalosiphum padi L.; Coccinella septempunctata L.; residues; volatiles; track; aphid settling; aphid olfactory response;

    Abstract : Predatory ladybirds, as natural enemies of aphids, can influence their prey in various ways, for example by consuming them or making the aphids drop off from their host plants. In this study, I have examined whether aphids can respond to the semiochemicals released from ladybirds. READ MORE
