Iron biofortification in four non-heterotic red sweet cultivars of bell pepper.

The present work investigated the effects of iron (Fe) chelate soil application on the nutritional quality of fruits from four non-heterotic red sweet bell cultivars of pepper. The results showed that soil application of Fe-HBED (25-100 µmol Fe·kg soil) caused an increase in the Fe content (up to ca. 70 %) in the fruits of 'Mercedes' and 'Robertina' without a decrease in fruit quality.
