文摘
Studies concerning chilling requirements of sweet cherry are of great importance to improve phenological models.
Mainly the release of dormancy is still a black box in phenological modelling.
We investigated changes in sweet cherry buds of ‘Summit’ with respect to different physiological parameter in 2011/2012 and 2012/2013.
Our results suggest that ABA and the ABA-isomer in the sweet cherry buds regulate differentiated metabolic processes in the dormant stage and during bud growth and development.
