摘　　要：香椿萌发所需的有效积温一般随着温度的降低而不断增加;香椿于落叶前和落叶后移栽对萌芽时间和所需有效积温影响不大,香椿休眠属于非生理性休眠类型;恒温比变温处理萌发时间明显缩短;伤根处理萌发期推迟和有效积温增加。Total effective temperature that toon-sprouting needed generally increased with the decrease oftemperature. It had little effect to transplant toon sapling on sprout time and total effective temperature whetherbefore or after deblade phase. Toon dormancy property belonged to unphysiological type. Constant temperaturetreating abbreviated sprouting time obviously compared with variable temperature dealing. Root damage deal-ing suspended sprout time and increased total effective temperature.
