摘　　要：葱属植物在内蒙古地区适应性强,生境广,有较高的经济价值,是内蒙古半干旱草原和荒漠地区的主要植物成分。本试验提供不同的发芽条件,分析6种葱属植物种子的萌发特性,探究其最适发芽条件及发芽限制因素及休眠原因。试验结果表明,种皮的不透性及机械束缚作用是限制葱属植物种子发芽的关键性因素。通过去皮处理的种子发芽速度明显加快,发芽率显著提高。Allium species exhibit strong adaptability and wide distribution in Inner Mongolia,holding significant economic value and serving as a major component of semi-arid grasslands and desert regions in the area.This experiment aimed to analyze the germination characteristics of seeds from six Allium species under different germination conditions,exploring their optimal germination conditions,limiting factors,and causes of dormancy.The results indicated that seed coat impermeability and mechanical constraints were critical factors limiting the germination of Allium seeds.Seed germination speed significantly increased,and germination rates markedly improved after seed coat removal.
