Gravitropism in Plant Stems May Require Ethylene

RAYMOND M. WHEELER 1 and FRANK B. SALISBURY 1

Two inhibitors of ethylene synthesis in plants (cobaltous ion and aminoethoxyvinylglycine) and two inhibitors of ethylene action (silver ion and carbon dioxide) significantly delay the gravitropic response (upward bending) of mature dicot stems laid on their sides. This evidence suggests that ethylene may be required in the gravitropic response of shoots.
