摘要
目的:了解温度、光照等条件对夏枯草种子萌发的影响。方法:常规的发芽试验方法进行试验。结果:适宜温度条件下,光照与否对夏枯草种子发芽率影响不明显,温度不适时,光照为制约夏枯草种子发芽的主要因素;在12~36h浸种时间范围内,随着时间的增加夏枯草发芽率有所降低;5.25℃,夏枯草种子的发芽率呈现先升后降的趋势。结论:浸种12h,20℃光照条件,最适宜夏枯草种子的萌发。
Objective:To understand the effect of illumination,temperature on the germination of the Prunella vulgaris seeds.Method:The general germination method.Result:Illumination showed no clearly effect on the germination rate of the P.vulgaris seeds under proper temperature condition;However,illumination was the main factor to determine the germination rate of the P.vulgaris seeds when the temperature condition was unsuitable.The germination rate of the P.vulgaris seeds decreased with the time and increased when the marinating time was from 12 to 36 hours.When temperature reached 5-25℃,the trend of the germination rate increased at first and then decreased.Conclusion:The optimal germination condition of P.vulgaris seeds is 12 h of marinating time at the temperature of 20℃under illumination.
