WebSep 15, 2024 · 119 measured at high levels of chill accumulation, after 3.5 months under chilling treatments, where 120 deacclimation responses are likely maximized. At low chilling accumulation, the slope in Fig. 1c 121 would presumably be higher due to lower deacclimation rates (Kovaleski et al., 2024; Kovaleski, 122 FR2024; North et al., 2024). … WebNov 18, 2024 · A chilling accumulation model was derived based on both the endodormancy period and the dormancy depth of each cultivar. The results showed that − 1.9 to 12.0 °C was an effective range for chilling accumulation and that 2.1–4.0 °C was the most effective range for chilling accumulation. gradient of the blue line
