  2. 1. Effects of carbon dioxide and ozone on wheat crop yield and grain quality

    Author : Malin Broberg; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; koldioxid; ozon; vete; skörd; protein; stärkelse;

    Abstract : Atmospheric concentrations of carbon dioxide (CO2) and ozone (O3) have steadily increased since the industrial revolution. CO2 and O3 directly affect plant physiology, CO2 being an essential substrate for photosynthesis, while O3 is an oxidative agent causing damage to plant tissues. READ MORE

  5. 3. Nutritional and physicochemical characterisation of dietary fibre in wheat fractions

    Author : Lina Haskå; Avdelningen för livsmedel och läkemedel; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; dietary fibre; fructan; arabinoxylan; wheat; distillers grains; short-chain fatty acids; microbiota;

    Abstract : Dietary fibre is fermented in the colon to short-chain fatty acids (SCFAs), of which especially butyric and propionic acid may have health-promoting effects. One source of dietary fibre may be by-products from wheat, which are currently used as animal feed. READ MORE

    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biogas; anaerobic digestion; bioenergy; Cannabis sativa L.; hemp; energy crops; biofuel; methane; transportation fuel; renewable energy;

    Abstract : Biofuels are currently produced from agricultural crops, and an increasing use of crops for this application is expected in the EU in the years to come. The dominating crops cultivated in the EU for biofuel production today have a relatively large environmental impact. READ MORE

  7. 5. Signalling between plants and microorganisms

    Author : Ulrika Troedsson; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; symbiosis; Chitinase; rhizobium; mycorrhiza; plant; glucanase; Biology; Biologi;

    Abstract : Plants and microbes can interact in several ways. Plants can be attacked by different types of pathogens like fungi, virus and bacteria, but can also form symbioses with fungi and bacteria. Certain common antimicrobial proteins are produced by the plants regardless of the type of microbial interaction with the plant. READ MORE
