Sunitibala H, Damayanti M, Sharma GJ: In vitro propagation and rhizome formation in Curcuma longa Linn. Cytobios. 2001;105(409):71-82.
Turmeric (Curcuma longa Linn.) which is cultivated by underground rhizomes is a slow propagating species. Multiplication and callus induction starting from the rhizome buds and shoot tips of C. longa in MS medium was carried out. A combination of naphthalene acetic acid (NAA; 1.0 mg/l) with kinetin (Kn; 1.0 mg/l) or NAA (1.0 mg/l) with 6-benzylaminopurine (BAP; 2.0 mg/l) was optimum for rapid clonal propagation of turmeric. A concentration of 2.5-3.0 mg/l of 2,4-dichlorophenoxy-acetic acid (2,4-D) was found to be optimum for callus induction. Regeneration of plantlets from a callus was successfully conducted in MS medium supplemented with standard growth hormones for multiplication at 25 +/- 2 degrees C under a 16 h photoperiod. These plantlets were successfully transferred to the field. Plantlets (4-month-old) were incubated in a medium containing different concentrations of sucrose supplemented with NAA (0.1 mg/l) and Kn (1.0 mg/l) at 27 +/- 2 degrees C under an 8 h photoperiod for induction of rhizomes. In vitro rhizome formation was observed in media containing 6 and 8% sucrose. |
