Parameter estimates for the cherry cultivars used in the study.

Also included for comparison are the estimates for (Prunus serrulata var. spontanea) in Korea from Jung et al., (2006). Tc is represents the base threshold temperature, Rc is the is the required chilling units, and Rh is the required heating (anti-chill) units.本数据集还纳入了供对照参考的相关数据，即Jung等人（2006）针对韩国地区山樱花（Prunus serrulata var. spontanea）得出的估算结果。其中Tc代表基准温度阈值（base threshold temperature），Rc代表所需冷量单位（required chilling units），Rh代表所需热量（抗冷）单位（required heating (anti-chill) units）
