Abstract
Climate change and the spread of sweet cherry cultivation to warmer regions results in a higher frequency of fruit doubling in the world.
The current study investigated more than 200 sweet cherry cultivars and selected clones to identify the potential ability of low fruit doubling in both open field and protected greenhouse in China.
We found that most of the cultivars showed a high ratio of double fruit occurrence when the ambient temperature reached 35°C during the stage of flower bud differentiation.
The ratio of doubling was dependent on the cultivars, regions, and approaches of cultivation with or without protected facilities.
Two new cherry cultivars, ‘Lijing’ and ‘Jinjing’, developed by Shanghai Jiao Tong University, showed an extremely low ratio of doubling.
While ‘Tieton’ showed a very high doubling ratio (86.3%), ‘Lijing’ and ‘Jinjing’ showed 0 and 2% doubling fruit in protected house, respectively, after 35 days with ambient temperatures beyond 40°C.
