内蒙古农业科技 2014(3) :28-30 Inner Mongolia Agricultural 5cience And Technology 6 种花卉种子萌发特性的研究王志鑫 l ，徐贺2 ，朱冠宇 1 ，董乔1 ，郭金丽 1 (1.内蒙古农业大学农学院，内蒙古呼和浩特 01∞19;2.包头轻工职业技术学院，内蒙古包头 014035) 摘要:试验研究了 6 种花卉种子在不同温度及光照条件下的萌发特性。结果表明:在 Oh 和 12h 光照条件下，麦仙翁、须苞石竹、五彩石竹、高雪轮和花园鼠尾草种子的发芽率、发芽势和发芽指数明显高于 24h 光照条件:矮啻轮种子在 12h 光照条件下发芽率、发芽势、发芽指数明显高于其他处理。在 15-25C时，麦仙翁、须苞石竹、五彩石竹、高雪轮、花园鼠尾草种子的发芽率、发芽势、发芽指数较高;温度超过 25C时其发芽率、发芽势、发芽指数相对较低。矮雪轮种子试验温度高于 20C时，其发芽率、发芽势、发芽指数明显降低。关键词:花卉种子;萌发;温度;光照中图分类号:5541.9 文由标识码:A 1O.3969/j.四川∞7-0佣7.2014.03.014 文章编号:1∞7--0907(2014)03-0028-03 Study on Seed Ge缸nninationCαharact缸er也tic臼S of Six F10wers WANG Zhi-xin (College of Agronomy, Inner Mongolia A伊cultural University,Hohhot 01∞19，China) Abs仕act:The germination characteristics at different temperatures and different illuminations in Agrostemma gith怨。L.，D归nthω barbatus,Dianthus Chinensis ,Silene armeria, Silene pendula and Salvia farinacea wωanalyzed .The results showed that seed germination rate , germination vigour and germination index under Oh and 12h light conditions were significanùy higher than that under 24h light condition in A .gitlu聊 L.，D.barbatω， D.Chinensis , S.armeria and Sfarinace a; germination rate , germination vigour and germination index under 12h light condition were significanùy higher than that under other treatments for S.pendu1a.
