[Hairy root induction and in vitro cultivation of Pueraria lobata willa. ohwi].

ABSTRACT

OBJECTIVE: To study the hairy root induction and hormone-free in vitro liquid cultivation of Pueraria lobata (Willd) Ohwi. METHOD: Co-cultivation of super-virulent Agrobacterium rhizogenes R1601 with P. lobata leaves in vitro. RESULTS: Hairy roots of rapid growth, high branches and plagiotropism developed vigorously on the surface of leaves, exhibiting rapid growth and resistance to kanamycin in hormone-free medium in vitro. CONCLUSION: A method of hairy root induction with A. rhizogenes as well as a system hairy root liquid cultivation in vitro for P. lobata have been established.
