Abstract
Hairy roots of Senna alata transformed with Agrobacterium rhizogenes, strain ATCC 15834 were induced and grown in half-strength Murashige and Skoog (MS) medium. Effects of sucrose contents and hormones on the growth and sennosides A, B production were investigated. Hairy roots cultured on hormone-free half-strength MS medium containing 5% sucrose under dark condition mostly stimulated the growth of hairy roots and increased the content of sennosides A and B yielding (169 +/- 4) and (34 +/- 3) microg g(-1) dry wt, respectively.
