Lack of chilling not only led to a considerable delay in budburst but also caused substantial changes in the chronological order of species' budburst.
The results indicate that temperature requirements and successional strategy are linked, with climax species having higher chilling and forcing requirements than pioneer species.
In contrast to prior hypotheses, photosensitive responses were not restricted to climax or oceanic species.
In this study, we present a multispecies climate chamber experiment to test the effects of chilling and photoperiod on the spring phenology of 36 woody species.
