• Kinetin has a significant synergistic effect on IAA-induced ethylene production in hypocotyl sections of etiolated mungbean (Phaseolus mungo L.) seedlings when it is administered immediately after cutting. If the addition of kinetin was delayed, it became less effective. Kinetin-pretreated sections followed by incubation either in IAA or in IAA plus kinctin produced ethylene essentially at an identical rate to the one treated with IAA plus kinetin at zero time. However, the buffer-preincubated sections followed by incubation in IAA or in IAA plus kinetin shows a much reduced rate of ethylene production as compared with the one treated with IAA or with IAA plus kinetin at zero time, respectively. These results suggest that kinetin is required for the maximal stimulation of ethylene production only during the early mcubation period while IAA is required continuously throughout the incubation; the removal of IAA from the IAA-treated tissues causes an immediate cessation of ethylene production.
