Cherry Bloom Delay
Get the latest Cherry Bloom Delay news, research and developments covering flowering phenology, dormancy, climate change, frost risk and technologies that can influence or predict flowering time in cherry orchards. Coverage includes research on sweet cherry cultivars, chilling requirements, temperature responses and strategies to reduce frost-related crop losses.
Flowering time is influenced by the balance between winter chilling and spring heat accumulation. Warmer winters can reduce the accumulation of chill units and delay dormancy release in some regions, while warmer spring temperatures can accelerate bud development. These responses vary by cultivar and climate, making accurate phenology models increasingly important for orchard management under changing weather conditions.
Find updates on bloom-delay treatments, frost protection, climate-resilient varieties, phenology modelling and orchard management. Recent research from the University of Göttingen found that autumn applications of ethephon delayed flowering in the Kordia sweet cherry cultivar, although the response was not consistent across cultivars and higher treatment levels could reduce fruit set. Further trials are needed before the approach can be recommended commercially.
