Abstract
The effects of ethylene inhibitors and ethephon sprays on internal ethylene levels, spring bud break, fruit set, and yield were studied.
Ethylene inhibitors applied at the bud swell stage reduced internal ethylene levels at bloom time.
Aminoethoxyvinylglycine (AVG) was the most effective inhibitor that reduced internal ethylene levels in the peach buds.
Internal ethylene bud levels during quiescence were 40% lower and 50% higher in winter applications of AVG and Ethephon respectively.
This alteration of internal ethylene bud levels during quiescence had no effect on bloom delay, fruit set, and yield.
