Definition
A root development stage (PO:0007520) during which a radicle (PO:0020031) emerges from the seed coat (PO:0009088). [source: GR:Anuradha_Pujar, ISBN:3826331524, POC:curators]
Comment
The actual point of emergence from the seed coat (PO:0009088) may not be observed if the seed is underneath a growth medium. In a fruit (PO:0009001) with a persistent pericarp (PO:0009084), emergence from the seed coat may not be observed. If the fruit is a caryopsis, the dry pericarp is fused with the seed coat, and emergence from the pericarp is simultaneous with emergence from the seed coat. This term is used only for seed plants.
