Summary
Potato glycoalkaloids were determined in tubers, stems and leaves of twelve varieties resistant and susceptible to bacterial ring rot. No significant difference was found between the averages of both groups. The varietal differences in each group were large and parallel. Potato sprouts which contain large amounts of the glycoalkaloids were shown to be extensively invaded by the causal agentC. sepedonicum.
The resistance of some potato varieties to ring spot is probably not related to the presence of the glycoalkaloids.
Résumé
On a fait la détermination des glycoalcaloídes chez les tubercules, les tiges et les feuilles de six variétés de pommes de terre résistantes et de six variétés susceptibles à la flétrissure bactérienne. Les moyennes pour le contenu en glycoalcaloídes ne montrent pas de différences significatives entre les deux groupes. Bien qu’il existe de grandes variations dans le contenu en glycoalcaloídes d’une variété à l’autre, ces variations suivent cependant des tendances parallèles dans chaque groupe. On a par ailleurs démontré la présence de l’organisme pathogène,C. sepedonicum, dans de nombreux germes qui contiennent de très grandes quantités de glycoalcaloídes.
Il semble plus que probable que la présence des glycoalcaloídes chez les pommes de terre n’a rien à voir avec la flétrissure bactérienne.
