摘　　要：以两年生低需冷量设施栽培专用毛桃品种‘春捷’为试材,检测Ca2+在自然休眠过程中的动态变化。结果表明:在季节变化过程中,Ca2+动态变化与自然休眠进程一致。在此过程中,Ca2+可传递环境信号,诱导桃芽自然休眠和维持桃芽的深度自然休眠。To take advantage of two-year-old ＇Chunjie＇ peach, we studied the changes of Ca2＋ during the natural process of dormancy of peach buds. The results revealed that the changes of Ca2＋ was consistent with natural dormancy in the process of seasonal changes. In this process, Ca2＋ made effect as a messenger in signal transduction of environmental changes, induced the natural dormancy of peach buds, and maintained their deep natural dormancy.
