Biokartoffeln Organic Eprints
Berner, Alfred; Böhm, Herwart; Buchecker, Kirsten; Dierauer, Hansueli; Dresow, Jana; Dreyer, Wilfried; Finck, Maria; Fuchs, Alexander; Keil, Sven; Keiser, Andreas; Kühne, Stefan; Landzettel, Christian; Mahnke-Plesker, Sylvia; Six, Roswitha; Speiser, Bernhard; Tamm, Lucius; Völkel, Günther.
Das Merkblatt vermittelt eine gute Basis für den erfolgreichen Anbau von Biokartoffeln. Besonderes Augenmerk wird auf die Qualitätssicherung gelegt. Zu jedem Anbauschritt zeigen die Autoren auf, wie sich welche Wachstumsfaktoren auf die Qualität des Endproduktes auswirken. Wo möglich werden konkrete Massnahmen zur Sicherung einer guten Knollenqualität empfohlen. Der von erfahrenen Beraterinnen und Forschern aus Deutschland, Österreich und der Schweiz verfasste Praxisleitfaden ist mit zahlreichen Fotos, Grafiken und Tabellen versehen.

Establishment of potato variety performance trials under growing regimes Organic Eprints
In order to select potato varieties suitable for organic production, information is required on yield, marketability, post-harvest storage performance and disease and pest resistance of different potato varieities grown under organic conditions. This project will aim to study selected potato varieitiess growing under organic conditions in order to provide information on the following: general field performance, with emphasis on characteristics important for organic conditions (e.g. speed of emergence, ground cover, foliage blight), and comparison with results from non-organic sites; yield and marketability prior to and after storage; the incidence of a range of common skin disorders (e.g. common scab, black scurf, silver scurf, black dot netted scab); the...

Qualitätssicherung bei der Langzeitlagerung ökologisch erzeugter Möhren Organic Eprints
Von 25 Möhrenschlägen auf Marschböden im Bereich der schleswig-holsteinischen Westküste wurden in der zweiten Septemberhälfte 2003 Pflanzenproben gezogen und deren Besatz mit Lagerkrankheiten qualitativ bestimmt. Von den Ende Oktober maschinell geernteten Möhren wurde je Fläche eine Probe gezogen und in einem maschinengekühlten Lager bei 0 – 0,5 °C und ca. 95 % rel. Luftfeuchte etwa 4 Monate lang gelagert. Anfang März 2004 wurden die krankheitsbedingten Lagerverluste und die sie verursachenden Lagerkrankheiten bestimmt. Obwohl zwischen dem Krankheitsbesatz vor und nach der Auslagerung nur wenige Übereinstimmungen bestanden, ließ sich unter Verwendung weiterer Daten zu Fruchtfolge, Stickstoffniveau im Boden und dem Anteil beschädigter Möhren im Lagergut...

The influence of the fungal pathogen Mycocentrospora acerina on the proteome and polyacetylenes and 6- methoxymellein in organic and conventionally cultivated carrots (Daucus carota) during post harvest storage Organic Eprints
LOUARN, Sébastien; NAWROCKI, Arkadiusz; Edelenbos, Merete; JENSEN, Dan Funck; NØRREGAARD JENSEN, Ole; Collinge, David B.; Jensen, Birgit.
Carrots may have to be discarded during post harvest cold storage due to development of fungal infections, caused by, e.g., liquorice rot caused by Mycocentrospora acerina. Control of this disease is mainly based on cultural practice. We compared the susceptibility of carrots grown under conventional and organic agricultural practices. We have developed a bioassay for infection studies of M. acerina on carrots and observed that organic roots were more susceptible after one month storage than conventional ones but no differences were apparent after four or six months storage. Levels of three polyacetylenes (falcarinol, falcarindiol and falcarindiol-3-acetate) and the isocoumarin phytoalexin (6-methoxymellein) were analysed. No changes in individual and...
