Abstract:
In order to identify the germination behavior of Marsdenia tenacissima seeds. We studied on ground substance, soaking time, temperature, illumination, and pH value, which have the effects on the germination of M. tenacissima seeds. The results showed that M. tenacissima seeds can germinate in different ground substances especially in sandy soil, the effect of soaking time on the seed germination of M. tenacissima is not significant, the seeds could germinate well during 25-30℃. Based on these appropriate conditions, the effect of illumination is not significant but the illumination should be the key factor under inappropriate temperature. The effect of acidic soil is lighter than that of alkaline soil. The optimal germination condition of M. tenacissima seeds is 24 h of soaking at the temperature of 30℃ with sandy soil by which pH value is 7.0-7.5 under illumination.
