  2. 1. Antioxidant Capacity in Fruit and Vegetables -Cultivar Variation - Storage Conditions - Human Antioxidant Status

    Author : Jessica Nilsson; Tillämpad biokemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; human plasma antioxidants; Brassica; strawberry; pea; cultivar; ABTS; FRAP; Total antioxidant capacity; TAC; Food and drink technology; Livsmedelsteknik;

    Abstract : The health-promoting effects of fruits and vegetables have been extensively discussed during the past decade since epidemiologic studies have shown relations between increased intake of fruit and vegetables and decreased incidences of several chronic diseases. It has been suggested that antioxidants are a main contributors to the observed effects, for example by acting as scavengers of free radicals. READ MORE

  4. 2. Bioactive Carbohydrates in Vining Peas (Pisum sativum) - Variation in alpha-galactoside content and the colonic fermentation of sugar alcohols

    Author : Jimmy Ekvall; Avdelningen för livsmedel och läkemedel; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; alpha-galactosides; raffinose family oligosaccharides; Näringslära; Nutrition; short-chain fatty acids; colonic fermentation; myo-inositol; sorbitol; xylitol; sugar alcohols; blanching; maturity; cultivar; Pisum sativum;

    Abstract : The composition of the colonic microflora is essential for the health of the human host. To be able to survive, the microflora is dependent of a continuous supply of substrate. In this respect dietary fibre and other indigestible carbohydrates, of which the consumption in affluent societies is generally low, are of great importance. READ MORE

  6. 4. Volatile mediated plant-plant communication in cultivar mixtures : from plant to aphid responses

    Author : Iris Dahlin; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Modern agriculture is characterized by simplified cropping systems, associated with negative effects on environment, biodiversity and biological control potential. Cultivar mixtures are often presented as a more efficient and sustainable alternative due to additive effects of cultivar properties and pest reduction, but previous studies have provided equivocal results for this claim.

  7. 5. Insect-plant interactions within cultivar mixtures : volatile plant communication as an underlying mechanism

    Author : Sokha Kheam; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Promoting genotypic diversity of crops via cultivar mixtures presents a promising strategy to sustainably control insect pests and diseases, and thereby enhance yield. However, the underlying mechanisms responsible for reduced pest performance in cultivar mixtures remain unexplored. READ MORE
