Description: The wide maturity distribution found in most peach varieties has always been a problem for machine harvesting. Plant breeding may eventually solve this problem however, the use of plant growth regulators may be a short-term solution. Knowledge about the effects of the plant growth regulator ethephon on peach maturity and its use as an aid to machine harvesting is limited. Sims (1971) found that ethephon advanced the harvest date of many peach varieties. Sims (1973) and Sims et al. (1973) also showed that ethephon applied 2 wk before harvest advanced maturity without pre-harvest drop, and promoted more uniform maturity. Ethephon was applied (Rom and Scott 1971)at rates from 250 ppm and 1500 ppm to Babygold-9 peaches just prior to harvest. The maturity was advanced as measured by fruit firmness, skin color and flesh color. Looney (1972) applied ethephon, and a combination of SADH and ethephon to Redhaven peaches at pit hardening and found both treatments to advance maturity. The purpose of this study was to determine the effects of ethephon on the physical properties of the Babygold-5 peach and to evaluate the use of ethephon as an aid to machine harvesting.
