黄连种子发芽条件的研究

Study on the Seed Germination Conditions of Coptis chinensis Franch

以石柱黄连种子为研究材料,采用不同的发芽床、温度、光照及不同生理时期的黄连种子,观察其萌发特性以寻找最佳萌发条件,提高成活率。结果表明,黄连种子发芽率低,发芽期长,贮藏期应不低于180 d,在12℃、低光照的土床环境下发芽情况较好。

With the seeds of Coptis chinensis Franch as materials, the seeds of C. chinensis with different germination bed, temperature, illumination and physiological stages were collected from Shizhu to find out the optimum conditions for their germination and improve their livability. The results showed that the seed of C. chinensis had low germination rate, long germination period, storage period of not less than 180 d. Optimum germination was observed when the seeds were cultured on soil bed under the conditions of 12 ℃, low - light intensity. Key words Coptis chinensis Franch ; Seed; Germination conditions
