Micropropagation of Turmeric (Curcuma longa Linn.) through in vitro Rhizome Bud Culture

K. Nasirujjaman, M. Salah Uddin, S. Zaman and M.A. Reza

Abstract

An ideal micropropagation method of turmeric (Curcuma longa Linn.) has been developed using rhizome bud explants. Woody Plant Medium supplemented with different concentrations of BAP alone or in combination with different concentrations of NAA produced varying degree of multiple shoots. A supplementation of 4.0 mg L 1 BAP + 1.0 mg L 1 NAA gave the best result. In this case, 95% of the inoculated explants induced multiple shoots within 8-10 days of inoculation and the average number of shoots per explant was 6.70. Rooting was spontaneous in almost all the treatments. Most of the regenerated shoots were successfully transferred to soil under field conditions.
