摘 要：
选择适当的种子引发剂种类、浓度以及适宜的引发时间是提高烤烟种子活力、打破种子休眠、促进种子萌发的有效手段。试验结果表明,3号引发剂具有很好的引发效果,48h是适宜的引发时间。引发技术有利于烤烟种子萌发过程中淀粉酶活性的提高。引发处理的烤烟包衣种萌发速度快,出苗相对集中,即使在低温条件下也表现较明显的优势。

摘 要：
Experiments on seed priming techniques of flue-cured tobacco were carried out.The results showed that suitable reagent and time could improve the vigor and germination of flue-cured tobacco seed and break its dormancy.No.3reagent had better priming effect than others,48hours might be the most favor-able priming session.The germination and emergence synchronism of the primed seeds were improved re-markably,even under stress conditions of low temperature,priming technique could improve the activity of amylase in the stage of seed germination.The germination of pelleted primed seed was quick and uniform,even under lower temperature,the primed seeds were superior to the common seeds of flue-cured tobacco.
