Leaf spray with Ti(IV) ascorbate improves the iron uptake and iron activity in Capsicum annuum L. plants

1995

Leaves of paprika pepper (Capsicum annuum L., cv Negral) plants sprayed with Ti(IV)-ascorbate showed an important increase of iron and titanium concentrations, as well as of the activity of peroxidase and catalase enzymatic systems. Leaf-Ti increase is similar for both greenhouse and field crop experiments, but increases in leaf Fe are more marked in plants growing under field conditions.
