Maoyuangen is the main growing part of Danshen, which has rich diterpenoid compounds. The aim of this study is to optimize the culture conditions of Danshen maoyuangen and investigate the effects of exogenous hormones on its secondary metabolism. Different culture media, growth regulators and light cycle conditions were used to optimize the culture conditions of Danshen maoyuangen, and the differences in growth activity and secondary metabolite content were compared. The results showed that adding 0.5 mg/L 6-BA, 0.1 mg/L NAA and a light cycle of 16 h/8 h (light/dark) in the MS medium can promote the growth of Danshen maoyuangen and the accumulation of diterpenoids.Keywords: Danshen maoyuangen; culture condition optimization; exogenous hormones; secondary metabolism1.讨论背景和意义丹参（Salvia miltiorrhiza Bunge）是一种广泛应用于中药临床的重要中药材，具有镇痛、抗炎、抗菌、保肝等多种功效。其次生代谢产物丹参酮及其衍生物是丹参主要的药用成分，具有广泛的生物活性。毛状根是丹参的主要生长部位，也是丹参酮类成分的重要来源。因此，讨论丹参毛状根的培育条件优化和次生代谢的调控，对于丹参的生产和开发具有重要的意义。精品文档---下载后可任意编辑外源激素是影响植物生...
