ACC research in olives with Becky Wheeler-Dykes
Fruit removal is a serious issue in table olive production, namely because the fruit are harvested before they are ripe. ACC, an ethylene precursor, has the potential to improve fruit removal (please note that the commercial product is not registered in olives yet and cannot legally be used).
Becky Wheeler-Dykes, an advisor in Glenn, Colusa, and Tehama Counties, has been examining its efficacy in olives with a team of researchers at UC Davis. She shares some preliminary, and promising results in this week’s episode.
