Briefings

A 2026 study led by the University of Göttingen found that ethephon, a plant growth regulator, can delay flowering in Kordia sweet cherry varieties to protect against late spring frost. The treatment failed to significantly delay flowering in two other sweet cherry varieties or two apple varieties, emphasizing the need for cultivar-specific selection. Results were published in BMC Plant Biology.

Key points

• A study led by the University of Göttingen found that ethephon can delay flowering in Kordia sweet cherry varieties to protect blossoms and developing fruitlets from late spring frost.
• The treatment did not significantly delay flowering in a second sweet cherry variety or two apple varieties, highlighting the importance of crop and cultivar selection.

Context and limitations

The evidence is from a 2026 study published in BMC Plant Biology, with specific limitations regarding the exact date of the study's publication and the snapshot of cherry varieties tested.
