Abstract
About 4 hours after they are cut from the seedling, corn (Zea mays L.) coleoptile segments mounted vertically show a strong increase in growth rate. This increase occurs in water or various buffers near pH 7 and is not accompanied by the accumulation of a growth promoter in the medium. The increase in growth rate is prevented by 1 mmp-fluorophenylalanine and is strongly inhibited by 0.1 mmp-chlorophenoxyisobutyric acid.Keywords
