1.3-radicle emergence stage
type: Class
subclass of: 1.3-radicle and coleoptile emergence stage
definition: The radicle and its enclosing sheath, the coleorhiza, breaks through the pericarp. In some rice varieties the coleoptile emerges before the radicle.

1.3-radicle and coleoptile emergence stage
type: Class
subclass of: 01-germination
definition: The radicle with coleorhiza and coleoptile, enclosing the plumule, breaks through the pericarp. In some rice varieties the coleoptile and radicle emergence may occur together or preceed either depending on the rice variety.
