Micropropagation of Karonda (Carissa carandas) through shoot multiplication

Shoot tips from field grown, mature plants of Carissa carandas cv. Pant Sudarshan were cultured on Murashige and Skoog's (MS) basal medium supplemented with benzyladenine (BA) and indolebutyric acid (IBA) during different seasons. The maximum sprouting rate was obtained with 1.5 cm long explant collected in spring season (February-March) followed by those collected in summer season (April-June). Shoot proliferation was highest on MS basal media supplemented with 3.0 mg l−1 BA. Rooting of microshoots was noted to be the best in 1/2 MS plus 0.8 mg l−1 IBA and 0.2 mg l−1 naphthalene acetic acid (NAA). The rooted plantlets were successfully acclimatized in vermiculite:sand:soil (1:1:1) potting mixture.
