Última Resistance against Fusarium spp. in narrowed leafed lupin (Lupinus angustifolius L.) Organic Eprints Jørnsgård, Bjarne; Kuptsov, Vladislav; Jensen, Birgit; Bødker, Lars; Knudsen, Jens Christian; Nielsen, John. L. angustifolius genotypes susceptible to Fusarium root rot and wilt can be grown in new lupin land without disease symptoms, however, lupin root rot and wilt pathogens build up during repeated cropping of susceptible lupins in the same field. After four lupin crops symptoms of root rot and wilt began in an inhomogeneous pattern over the field, and after another three lupin crops susceptible lupins are destroyed before flowering homogeneously over the field and caused total crop failure. The dominating pathogens isolated from diseased lupins with root rot and wilt symptoms in this field are in descending order F. oxisporum, F. solani, F. culmorum, and F. avenaceum, the latter only being isolated from young autumn sown plants. A core collection of lupin... Tipo: Journal paper Palavras-chave: Crop health; Quality; Protection Breeding; Genetics and propagation. Ano: 2007 URL: http://orgprints.org/10996/1/10996.pdf Comparison of extraction methods for analysis of flavonoids in onions Organic Eprints Soeltoft, Malene; Knuthsen, Pia; Nielsen, John. Onions are known to contain high levels of flavonoids and a comparison of the efficiency, reproducibility and detection limits of various extraction methods has been made in order to develop fast and reliable analytical methods for analysis of flavonoids in onions. Conventional and classical methods are time- and solvent-consuming and the presence of light and oxygen during sample preparation facilitate degradation reactions. Thus, classical methods were compared with microwave (irradiation) extraction, ultrasonic liquid extraction and accelerated solvent extraction.

The objective of the PhD-project is to characterize bioactive metabolites, such as polyphenols, in selected crops and investigate the influence of different organic farming systems on the ability of crops to synthesize bioactive compounds with health promoting effects. The study includes two organic and one conventional farming system and is part of the OrgTrace project (content, bioavailability and health effects of trace elements and bioactive components in organic agricultural systems), where harvest takes place in autumn 2007 and 2008.
