Zusammenfassung
Handelsübliche Gewürze vonPimpinella anisum (Anis) undCuminum cyminum (Cumin) wurden mit 2,5 und 5,0 μg/ml Aflatoxin B1 versetzt, um zu entscheiden, ob niedrige Konzentrationen die Keimung und die Wurzelverlängerung beeinflussen. Diese Mengen haben aber die Keimung der Samen von Anis und Cumin nicht verhindert. Es gab jedoch eine bedeutsame Verlangsamung der Wurzelverlängerung. Die größere Konzentration des Toxins führte auch zu einer stärkeren Verlangsamung, wobei beide Konzentrationen von Aflatoxin B1, die Wurzelverlängerung bei Anis bedeutsam verhindert haben, wogegen dies erst bei 5,0 μg/ml für Cumin eintraf. Diese Ergebnisse lassen den Schluß zu, daß erhöhte Aflatoxin-Konzentrationen sowohl der frühen als auch der späteren Entwicklung bei den Gewürzpflanzen schaden dürften.
Summary
CommercialPimpinella anisum (anise) andCuminum cyminum (cumin) seeds were allowed to imbibe with 2.5 and 5.0 μg/ml aflatoxin B1 medium to determine whether ;ow toxin concentrations might affect their germination and subsequent root elongation. This imbibition did not markedly inhibit either anise or cumin seed germination. However, there was a marked retardation of root elongation for both seed types. The higher toxin concentration caused a more severe degree of retardation. Whereas both aflatoxin B1 concentrations significantly inhibited anise root elongation, only 5.0 μg/ml medium significantly impaired this elongation for cumin. These results suggest that elevated aflatoxin levels within seeds could be detrimental to the early and perhaps the later development of both anise and cumin plants.
