摘　　要：苔草属(Carex)植物种类多,分布范围极广,适应性强,观赏价值高,是优良草坪及地被植物的新资源。可是,苔草属种子普遍具有很强的休眠特性,萌发率低,发芽起始晚,以及夏季次生休眠的诱导,故长期以来限制了苔草植物在草坪中的应用。总结了国内外苔草种子休眠和萌发的研究成果,对苔草种子的特性、休眠类型、休眠机制、破除休眠的方法、发芽需要的条件等方面进行了综述。同时,提出了今后苔草属种子休眠和萌发方面的研究方向。Genus Carex,with large number of species,almost occur in every type of habitats. Many of them have good adaptability and high ornamental value features, so Carex species are good and new turf ground cover resources. However,almost Carex species has a strict or conditional primary dormancy,low germination rate, late germination and induction of secondary dormancy in summer. All these characteristics limit establishment and restoration of Carex community. Many research achievements on dormancy and germination of Carex domestie and abroad was summarized in this paper. Carex and requirement are reviewed and discussed as well. At seed traits, dormancy types, mechanism, pretreatment the same time, several research fields have been discussed for further work about Carex seed dormancy and germination.
