De novo shoot regeneration from root cultures of Garcinia indica Choiss.


PMID 18697609

Abstract

Roots of plantlets of Garcinia indica when cultured for long time on half strength MS medium supplemented with BAP (0.44-2.22 microM) showed production of de novo shoots. Roots attached to mother plant showed more number of shoots, while excised root segments produced lesser shoots. Shoots (0.5-0.8 cm) were transferred to elongation medium consisting of Woody Plant Medium (WPM) supplemented with BAP (4.44-22.69 microM), IAA (5.71 microM) and kinetin (4.65 microM). It was observed that shoot length increased to 1-2 cm. WPM medium supplemented with NAA (2.69-10.74 microM) and IBA (4.90 microM) induced rooting within 20-25 days. Using the present protocol, 20-25 plantlets could be regenerated from single root explant within 3 to 4 months. The protocol has potential for large scale production of elite plants.
