Homorhizia

Homorhize rooting in maize

In botany, homorhizia is a type of rooting that is opposed to allorhizia . The root system consists only of morphologically equivalent roots and arises from sprouting roots.

There are two types of homorhizia:

• Primary homorhizia: rooting type of vascular pore plants such as ferns , in which all roots can be regarded as sprouting and thus no main root can be identified.
• Secondary homorhizia: Rooting type of the monocotyledons ( monocotyledons ) and individual dicotyledons ( dicotyledons ), in which all roots can be regarded as sprouting , but in which the main or radicle dies early in ontogenesis .

The term is made up of the prefix homós ( Greek  ὁμός ) “equal” and rhizoma ( Greek  ῥίζωμα ) “rooted”.
