摘　　要：以‘香瑞白’梅为试验材料,研究了黑暗处理、变温层积、单独使用赤霉素(GA3)或低温层积,以及赤霉素和低温层积、去内果皮相结合的方法对‘香瑞白’梅种子萌芽率的影响,结果表明:以质量浓度为150、300 mg·L-1GA3对‘香瑞白’种子进行浸泡处理,并结合90 d低温层积,种子发芽率最高,可达30%;与不去内果皮处理相比,去内果皮处理能显著提高种子发芽率;全黑暗处理能显著提前‘香瑞白’梅种子的初萌期,且发芽率比光暗交替处理提高了1倍;变温层积处理对种子萌芽率的影响并不显著,萌芽率为0。For improving the seed germination rate of Prunus mume, the experiment was conducted to investigate the effects of different pretreatments on the seed germination of P. murne ＇ Xiang Rui Bai＇ The pretreatments included darkness processing, warm and cold stratification, Gibberellin A3 （ GA3 ）, cold stratification, and GA3 combined with cold stratification and removing endocarp. The highest seed germination rate is 30% when GA3 content is around 150 or 300 mg ·L-1 for 90- day chilling. The seed germination rate can be enhanced significantly by removing endocarp compared with that without endocarp. Darkness treatment can obviously advance the sprout date of P. mume ＇ Xiang Rui Bai＇ seed and generation rate is doubled. There is no significant effect on seed germination under warm and cold stratifications with germination rate of 0.
