Agronomical and chemical variability of Colchicum autumnale accessions Inra
Poutaraud, A.; Girardin, P..
Le colchique (Colchicwn autunznale) est une plante à alcaloïdes non domestiquée. La colchicine et le colchicoside extraits des graines sont utilisés dans plusieurs médicaments. Un programme de recherche a été développé pour domestiquer cette plante et produire des graines pour l’industrie pharmaceutique. La variabilité inter et infra origine(s) de caractères agronomiques et chimiques aété étudiée. La colchicine, la 3-demethylcolchicine et te colchicoside ont été dosés en chromatographie en phase liquide. Six origines ont été prélevées sur des sites naturels & l’Est & la Fiance et cultivées sur deux sites pendant un ou deux ans. Des plantes provenant de soixante dix connus repiqués ont été étudiées individuellement pendant quatre ans en vue...

Characterisation of a new potyvirus species infecting meadow saffron (Colchicum autumnale) Inra
Poutaraud, A.; Desbiez, C.; Lemaire, O.; Lecoq, H.; Herrbach, E..
The alkaloids contained in Colchicum autumnale seeds are used in numerous medicines. Good quality seeds are difficult to obtain from this undomesticated plant. Therefore, a research program was set up aiming to cultivate C. autumnale in order to improve alkaloid contents and seed yields. In this context, a collection was established in 1999 by transplanting corms from twelve different locations in Eastern France. However, serious symptoms of necrosis and decay have appeared in this collection since 2001. Electron microscopic observations of plants showing symptoms revealed the presence of filamentous particles and pinwheel-like structures characteristic of the Potyviridae family. Leaves and corms from symptomatic plants were assayed with potyvirus-specific...
