摘　　要：概述了植物种子休眠类型及其破除方法的研究情况。种子休眠主要有由种皮引起的种壳休眠和由胚引起的胚休眠2种类型。然而,实际上有些种子因复杂多样的各种因素影响同时存在着这2种休眠类型,继而破除种子休眠的方法也复杂多样。破除休眠方法主要有温度处理、机械处理、层积处理、光照处理、激素处理、化学药剂处理。对于综合休眠类型的植物种子,采用综合方法来破除休眠的效果较单一处理方法更加显著。The researches on the seed dormancy types and the breaking methods were summarized.There are basically two categories of dormancy,one is caused by seed coat,the other is caused by embryo.In fact,seed dormancy is very complicated,there are two sleep types at the same time,because of being influenced by complex and diverse variety of factors,then the way of breaking seed dormancy also will be complex and diverse.The dormancy breaking methods include temperature treatment,mechanical treatment,stratification,light treatment,hormone treatment,and chemical treatment.And using the comprehensive methods to break dormancy is more effective than a mono-treatment for those seeds that induced dormancy by complicated factors.
