Morinda citrifolia L. is a valuable medicinal plant, used to treat many diseases, such as sleeplessness, backache, high pressure... Recent studies show that Morinda citrifolia L. can regenerate adventitious roots in-vitro. To study the root morphogenesis in Morinda citrifolia L., we examined the effects of some auxin on regeneration of adventitious root in hypocotyl and leaf. The results showed that the concentration of 0,1mg/l NAA stimulated the formation of callus and primordia root in hypocotyl and leaf, in the first week, and the elongation of primordia root in the second week. Roles of respiration rate and endogenous hormones were discussed to understand the physiological changes in the formation of adventitious root.
