分析了蔷薇(Rosa L.)种子休眠原因、解除休眠方法以及环境条件对休眠与萌发的影响.蔷薇种子休眠的主要原因有瘦果果皮和种皮的限制作用,胚生理休眠以及果肉、瘦果果皮、种皮和胚中的抑制物质.解除休眠的方法包括去除瘦果果皮限制、解除胚的生理休眠、去除抑制物质等.种子发育过程中及成熟后,环境因子,如温度、水分和光照,对种子休眠和萌发有影响.此外,微生物、果实采集时间也对种子休眠及萌发有较大影响.蔷薇种子的休眠机制复杂,且种间差异很大.

The reasons of dormancy,methods of breaking dormancy,and the effect of environment factors on dormancy and germination of Rosa Seeds were analysed.There Were some resons caused Rosa seeds dormancy,such as the restriction of pericarp and testa,physiological dormancy in embryo and inhibitory substances in pericarp,testa and embryo.Therefore,breaking dormancy methods in some Rosa plants were also reviewed,including derestriction and removing inhibitory substances,etc.The environment factors,such as temperature,water and light had important effects on seed dormancy and germination during development and ripening stages.Otherwise,microbial action and the time of hip collection affected seed dormancy and germination of Rosa plants.The dormancy mechanism of Rosa seeds was complex,and had great differences among various Rosa species.
