Among the five factors， soaking time had the greatest effect on germination rate. The soaking time of hybrid based on optimal germination （ 12h ）was shorter than that of parent （ 24h ）. The above research has important theoretical and practical significance for improving the popularization and application of Viola tricolor varieties.

三色堇（Violatricolor）原产北欧，别名猫儿脸花、蝴蝶花、鬼脸花，为堇菜科堇菜属一、二年生花卉，性喜冷凉，较耐寒，花色丰富、花期长、观赏性极强，是大花三色堇（ Viola×wit- trockiana）和小花三色堇（Viola × williamsii）的重要杂交亲本，其商业品种是冬春盆栽花卉、花坛、花境、地被用花等常用类型，弥补了我国冬季露地开花植物较少的不足[1-2]。（剩余5846字）
