- After fertilization, several achenes are produced per capitulum, and seeds are wind-dispersed.
- Thrips may also cause blemished seeds on achenes, and uneven maturity of fruit.
- It has previously been shown that, in strawberry fruit, the expression of some ripening-related genes are directly or indirectly negatively regulated by the auxins produced in the achenes.
