Abstract

Surgical removal of the coleoptiles from germinating seedlings of Secale cereale L., Avena sativa L., and Zea mays L. leads to a total loss of gravitropic response of the shoot without affecting growth. The principal function of coleoptiles is therefore to guide the gravi-insensitive shoot to the soil surface.
