e0“The effect of ethephon on flowering and cropping of strongly alternate bearing spur-type `Delicious' apple ( Malus domestica Borkh.) was evaluated in a 6-year study”
e4“Ethephon reduced both the variation in yield, particularly in “off years,” and the magnitude of alternation”

- Intervention effect Ethephon-treated trees had 10% less yield distribution in on years.
- Intervention effect Ethephon reduced the magnitude of alternation.
- Intervention effect Ethephon-treated trees initiated more flowers per kilogram of fruit produced than the controls.

- Observation Ethephon-treated and control trees did not differ in the amount of fruit produced per unit bloom density.
- Observation Internal ethylene concentration, firmness and starch index were not significantly affected by ethephon.
- Observation Soluble solids and colour were not significantly affected by ethephon.
- Observation Internal ethylene concentration and starch index tended to be higher in fruit from ethephon-treated trees.
