Cover Story: To model the onset of sweet cherry blossom, it is necessary to know the cycle of bud development, including the timings of unobservable dormancy phases. This study compares three phenology models (M1–M3); only M3 contains enough physiological insight to outperform the other models. Our results suggest that, for a physiologically based modeling approach, at least the date of endodormancy release (t1), the onset of ontogenetic development (t1*), and the bud abscisic acid (ABA) content during ecodormancy (t1–t1*) should be known. The study highlights the time-dependent inhibition of bud development by ABA during ecodormancy. Thus, simple inverse modeling approaches, such as M1, are not able to capture the ecodormancy phase and carry the risk of incorrect parameter estimation, which may lead to erroneous conclusions about the cultivation of fruit varieties due to climate change.
