The cherry crop is one of the most important horticultural crops both nationally and internationally. In terms of production, Romania is in the top ten countries worldwide, more precisely it ranks ninth, with a production of 682.010 tons recorded in the last ten years. At Fruit Research and Development Station Bistrita, 12 varieties with different ripening periods were monitored during the last three years (2018-2020). Objective of the research was to assess the phenological response to climate change and the behavior of some Romanian and foreign bred sweet cherry cultivars. Observations were made throughout the year for each phenophase. Following the data obtained, the number of days assigned to each phenophase was determined, for each year studied (2018-2020). Results reveals that the instability of climatic factors directly influenced the vegetation period of the cherry crop. Data showed that in the inflorescence emergence and flowering period due to climate change events there is a possible risk for late frost events. Phenology datasets in relationship with weather data modelling are bioindicators for climate change events and are key elements in fruit crop technology.
