title: Micropropagation of Hedychium coronarium J. Koenig through rhizome bud.
abstract: An optimized protocol was developed for in vitro plant regeneration of a medicinally important herb Hedychium coronarium J. Koenig using sprouted buds of rhizomes. The rhizomes with sprouted bud were inoculated on Murashige and Skoog (Physiol Plant 15:473-497, 1962) medium (MS) supplemented with either N(6)-benzyladenine (BA) alone (1.0-4.0 mg L(-1)) or in combination with 0.5 mg L(-1) naphthalene acetic acid (NAA). Of these combinations, MS supplemented with a combination of 2.0 mg L(-1) BA and 0.5 mg L(-1) NAA was most effective. In this medium, best shoots (3.6) and roots (4.0) regeneration was observed simultaneously with an average shoot and root length of 4.7 cm and 4.2 cm respectively. Regeneration of shoots and roots in the same medium at the same time (One step shoot and root regeneration) reduced the time for production of in vitro plantlets and eliminates the media cost of rooting. Cent-percent (100 %) success in plant establishment was observed in both gradual acclimatization process as well as when plants were directly transferred to outdoor in clay pots containing a mixture of garden soil and sand (2:1) without any sequential acclimatization stage.
