摘　　要：[目的]确定夏枯草种子最适发芽条件。[方法]夏枯草种子发芽试验中，温度设5个处理（17、19、21、23、25℃），浸种时间设7个处理（0、4、8、12、24、36和48h），光照设2个处理（光照、黑暗）探讨温度、浸种时间、光照对夏枯草种子萌发的影响。[结果]温度对夏枯草种子的发芽率、发芽势、发芽指数有显著影响，在17～25℃范围内，随温度升高，夏枯草种子的发芽率呈先升高后降低的趋势，发芽势在21℃下达最高值。为39％。浸种时间对夏枯草种子发芽有显著影响，在0～12h范围内。随着浸种时间的延长，发芽势逐渐升高；在24～48h范围内，随着浸种时间的延长，发芽势逐渐下降，光照有利于夏枯草种子发芽。[结论]夏枯草种子的最适发芽温度为21℃，夏枯草种平的蔷件滓种时间为12h。[Objective] The study aimed to determine the most suitable condition for germination of Prunella vulgaris seeds. [Method] In the experiment on the seed germination of P. vulgaris, five temperature treatments （ 17,19, 21, 23, 25 ℃ ）, seven treatments of soaking time （0, 4, 8, 12, 24, 36 and 48 h） were set up to explore the effect of temperature, time of soaking seeds and light on the germination of P. vulgaris seeds. [Result] Temperature had significant effect on the germination rate, germination energy, germination index of P. vulgaris seed. In 17 - 25 ℃, the germination rate of P. vulgaris seed was first increased and then decreased with the temperature increasing and the germinating energy arrived at a maximal value （39%） at 21 ℃ .Soaking time had remarkable influence on P. vulgaris seed germination.In 0 - 12 h, the germination percentage of P. vulgaris seed was increased gradually with the prolonging of seed soaking time; in 24 - 48 h, the germination rate of P. vulgaris seed was decreased gradually with the prolonging of seed soaking time,The light was beneficial to the germination of P. vulgaris seeds. [Conclusion] The optimum germination temperature for the seeds of P. vulgaris was 21 ℃ and the optimal soaking time was 12 h.
