It is a general characteristic of highland tropical maize, and it is often associated with an ability to emerge from planting depths of up to 25 cm because of mesocotyl elongation (Eagles and Lothrop, 1994).
Many warm-season grasses have panicoid seedling morphology in which seedlings emerge by elongation of the mesocotyl (also referred to as the subcoleoptile internode), while the coleoptile stays short (Hoshikawa, 1969; Hyder et al.
