Root-reducing capacity, rhizosphere acidification, peroxidase and catalase activities and nutrient levels of Citrus taiwanica and C. Volkameriana seedlings, under Fe deprivation conditions

Impact de la privation de Fe sur la capacite racinaire de reduction, l'acidification rhizospherique, l'activite de peroxidase et catalase ainsi que sur le niveau nutritif chez le Citrus taiwanica et le C. volkameriana. Le deficit en fer provoque par la privation, l'apport a faible dose ou l'addition de CaCO 3 /NaHCO 3 provoque des modifications physiologiques et biochimiques chez les souches du C. taiwanica et du C. volkameriana. Par exemple, le deficit en fer induit une augmentation de la capacite racinaire de reduction du Fe, ainsi qu'une acidification de la rhizosphere. Des plants de semis presentent une diminution de la capacite de reduction du fer lorsqu'ils sont traites avec une quantite suffisante de Fe (20 μM MM Fe-EDDHA). Le deficit en fer est associe a l'activite de la catalase et de la peroxidase. Il est egalement observe que la privation de Fe augmente la concentration de N, P, Ca, Mg, Mn et diminue celle de Fe et de Zn chez les feuilles jeunes des deux souches, C. volkameriana est plus sensible a la chlorose en fer que C. taiwanica.
