A, Effect of ethephon treatment at various concentrations compared with untreated sections (control) or with sections submerged for the same time (submerged). B, Effect of ethephon treatment in combination with NBD, an inhibitor of ethylene action, at the concentrations indicated. Controls were incubated without the addition of hormone or inhibitor. Results are averages ± se of at least seven stem sections.
