| dc.description.abstract | Problem encountered in bcukation of Cinchona species by A, rhizogenes is low percentage of transformed root initiation and slow growth of hairy root. Strains of A, rhizugenes and the growth medium has a significant effect to the formation of hairy roots. The aim of this research was to evaluate the potmtia1 of several A. rhizogenes strains far initiation of hairy roots of C. succirubra and C. ledgeriano, and to obtain the optimum composition of the medium for hairy roat culture of Cinchona species. | |
