The seminal roots continue to develop during the vegetative phase, but further adventitious (or nodal) roots start to develop about one to two months after germination. The adventitious roots derive from the coleoptile node or lower nodes of the main stem and tillers. They generally overtake the seminal roots and can occupy over 90–95% of the total root volume of a fully grown crop.
