| Abstract: | When sections of floating rice stems were treated with 1-aminocyclopropane-l-carboxylicacid (ACC) at 60% relative humidity, their ethylene contentincreased but internodes hardly elongated. The internodal elongationinduced by ethylene was promoted in sections incubated at 100%relative humidity but not at 20%. Thus, ethylene-induced internodalelongation in floating rice requires moist surroundings. (Received April 25, 1990; Accepted December 22, 1990) |
