ABSTRACT
Objective To study the effects of phytohormones and elicitors on the growth and anthraquinone production of Cassia obtusifolia hairy roots. Methods Blades and petioles of C. obtusifolia〖WTBZ〗 were infected with Agrobacterium rhizogenes LBA9402 and the in vitro culture system of the hairy root was established. Results Hairy roots were induced by A. rhizogenes LBA9402. The results showed that the addition of 0.5% NAA to the hairy roots increased the content of five kinds of anthraquinones by four times, and Aspergillus niger elicitor had no much effect and JA had slightly inhibitory effect on root growth, but both of them significantly promoted the anthraquinone accumulation, the anthraquinone yield increased more than two times with the treatment of 2.0 mL elicitor/50 mL medium and by 73% with the treatment of 10 ?mol/L jasmin acid (JA), respectively. JA had little inhibitory effect on the growth of fairy roots. Conclusion The fundation has been established for further oplimizing the proper cultural system for C. obtusifolia hairy roots and regulating the secondary melabolite.
