摘　　要：经层积处理解除休眠的水曲柳种子于10种不同温度条件下萌发的结果表明:变温条件下的种子萌发比恒温条件的好,最佳的变温条件为15℃/10℃,最佳的恒温条件是10℃,20℃以上的恒温会诱导种子产生二次休眠。The stratified seeds of Fraxinus mandshurica were germinated in ten temperature regimes. The results showed that the germination process under alternating temperature regimes was better than that under constant temperature regimes. The optimum alternating and constant temperature regimes were 15 ℃/10℃and 10℃ respectively, and a constant regime over 20℃would induce secondary dormancy.
