Synopsis

Synopsis

Varieties and selections with long coleoptiles emerged more rapidly than those characterized by shorter coleoptiles. Emergence rate indexes were found to parallel coleoptile length. Standard-height varieties produced longer coleoptiles than the semidwarfs for all depths at 50° F., while at 90° semidwarf selection 14 × 53-101 rated second at the 2-inch and 4-inch depths of planting. At the 3- and 4-inch planting depths emergence was reduced between 15 and 49% at 50° and 48 to 81% at 90° when compared to emergence percent at the 2-inch depth.
