Phase III - basal curvature and elevation


During the third phase of sprouting, a second center of curvature develops at the base of the propagules, just above the point where roots anchor them. This elevates the whole unit distal to the base.

Restrained propagules (the third from the front) continue to curve. No lifting of the base is visible yet, however. The epicotyl-less propagule toward the rear lifts higher, but with minimal curvature.
