Abstract
Ethephon (100 mg·liter -1 ) was applied to mature peach trees [ Prunus persica (L.) Batsch. cv Jerseydawn] on 1, 2, 3 or 4 dates beginning 15 Sept. 1990 at approximately 2 week intervals for a total of 12 treatments. Ethylene evolution from flower buds and flower bud phenology were monitored through bloom the following spring. Total flower bud density, live flower bud density, percentage live pistils, yield and number of fruit per tree were also measured. The response to multiple ethephon applications was greatly influenced by the timing of specific treatment combinations rather than by the total amount of ethephon applied over the course of the experiment. Ethylene evolution was elevated for about 2 weeks following application(s), however, no clear relationships between bud phenology or survival and ethylene evolution was observed. Several of the multiple ethephon applications significantly delayed bloom to the 75% pink stage, however, none of the treatments significantly influenced development to 75% balloon or fully open stages. Several of the multiple applications caused significant pistil mortality.
