Effect Of Iron Overload To Plants

The Effect of Excess Iron in Plants | Sciencing

Iron helps them create chlorophyll and aids in several other chemical processes plants perform. However, too much iron can have a toxic effect on the plant, weakening and eventually killing it. It should be noted that plants only absorb ferrous iron particles from the soil, and that other types of iron particles will not affect plants.

Iron stress in plants - PubMed Central (PMC)

30/07/2002· But iron is toxic when it accumulates to high levels. It can act catalytically via the Fenton reaction to generate hydroxyl radicals, which can damage lipids, proteins and DNA. Plants must therefore respond to iron stress in terms of both iron deficiency and iron overload.
