| Description |
In vitro microrhizome production was obtained in turmeric (Curcuma longa Linn.). Freshly sprouted buds with small rhizome portions excised from stored mature rhizomes were cultured on semi-solid culture initiation medium - MS basal medium + 0.88 muM BAP (6-benzylaminopurine) + 0.92 muM kinetin + 5% coconut water + 2% sucrose + 0.5% agar - resulting in bud elongation. Multiple shoots were produced from these elongated buds by culturing in liquid shoot multiplication medium - MS basal medium + 2.2 muM BAP + 0.92 muM kinetin + 5% coconut water + 2% sucrose - at 25+/-1 degreesC and 16-h light (at 11.7 mu mol m(-2) s(-1))/8-h dark cycles. Clumps of four to five multiple shoots/single shoots were used in various experiments. Cultures were incubated in the dark at 25+/-1 degreesC. Half strength MS basal medium supplemented with 80 g 1(-1) sucrose was found to be optimal for microrhizome production. Cytokinin BAP had an inhibitory effect on microrhizome production. At the highest concentration of BAP tried (35.2 muM) microrhizome production was totally inhibited. Microrhizome production depended on the size of the multiple shoots used. Microrhizomes produced were of a wide range in size (0.1-2.0 g) and, readily regenerated when isolated and cultured in vitro on culture initiation medium or shoot multiplication medium. Under in vivo conditions, small (0.1-0.4 g), medium (0.41-0.8 g) and big (>0.81 g) microrhizomes regenerated. Plantlets developed from big microrhizomes grew faster.
