摘要：

To enhance growth and rosmarinic acid production in catnip (Nepeta cataria L), hairy root cultures were grown for 15 days in media supplemented with various concentrations of auxins or polyamines. Three auxins (0.1-1 mg.L-1 IAA, IBA, and NAA) enhanced the growth of hairy roots and production of rosmarinic acid. IBA was the most effective auxin. Hairy root cultures treated with 0.5 mg.L-1 IBA produced the highest levels of growth (13.5 g.L-1 culture) and rosmarinic acid (19.2 mg.g(-1) dry weight). Similarly, putrescine was the most effective polyamine. Hairy root cultures treated with 50 mg.L-1 putrescine produced the highest levels of growth (13.3 g.L-1 culture) and rosmarinic acid (18.4 mg.g(-1) dry weight). These findings indicate that exogenous auxins and polyamines can enhance growth and rosmarinic acid production in hairy root culture of N. cataria.
