Extended Data Fig. 8: Relative contributions of changes in winter chilling and spring forcing to the changes in the leaf unfolding dates.
From: Deciphering the multiple effects of climate warming on the temporal shift of leaf unfolding
ΔLUD is the change in leaf unfolding date. ΔDdf0 is the changes in date when dormancy is released. ΔDFr is the potential changes in the duration (in day) of forcing stage caused by changes in spring forcing temperatures. ΔDTA0 is the potential changes in the duration (in day) of forcing accumulation stage caused by rising forcing requirement due to chilling deficiency. Violins with the black and red dots show the changes of each variable from 1951–1979 to 1980–1999 (black, ΔD1990s-1970s), and to 2000–2019 (red, ΔD2010s-1970s), respectively. The asterisks (**) indicate that the relative contribution of a specific factor to the shift of LUD from the reference period 1951–1979 to 1980–1999 is significantly (p<0.05 based on paired-samples t-test) different from that from the reference period to 2000–2019. In each violin plot, the balloon represents the probability density distribution of each gradient of R2. Whiskers indicate the interquartile (thick vertical bars) and 95 % confidence intervals (thin vertical bars). AH: Aesculus hippocastanum; AG: Alnus glutinosa; BP: Betula pendula; FS: Fagus sylvatica; FE: Fraxinus excelsior; QR: Quercus robur.
