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0h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;矮雪轮种子在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15~25℃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25℃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20℃时,其发芽率、发芽势、发芽指数明显降低.

Abstract: The germination characteristics at different temperatures and different illuminations in Agrostemma githago L.,Diauthus barbatus,Dianthus Chinensis ,Silene armeria, Silene pendula and Salvia farinaeea was analyzed .The results showed that seed germination rate, germination vigour and germination index under Oh and 12h light conditions were significantly higher than that under 24h light condition in A.githogo L.,D.barbatus, D.Chinensis, S.armeria and S.farinacea; germination rate, germination vigour and germination index under 12h light condition were significantly higher than that under other treatments for S.pendula. Germination rate,germination vigour and germination index of seeds were higher at temperature of 15℃-25℃ in A. githago L.,D. barbatus,D.Chinensis,S.armeria,S.pendula and S.farinacea, and they were relatively lower at temperature higher than 25; Germination rate, the germination vigour and germination index of S.pendula were significantly reduced at temperature higher than 20℃.
