    Opis:
    A method for vegetative propagation of Moringa concanensis was developed in the present study. Stem cuttings were collected from wild populations in Tamil Nadu. The cuttings with 2-4 nodes were treated with various concentrations of Indole Butyric acid (IBA), Indole Acetic Acid (IAA) and α-Naphthalene Acetic Acid (NAA) for 5 min. The effectiveness of auxins on shoot bud induction and rooting response of stem cuttings was in the order of IBA>NAA>IAA. The auxin treated cuttings were planted on planting media and placed in the greenhouse. The survival rate and relative growth rate of stem cuttings were analyzed at every 4 week interval for 24 week. Stem cuttings treated with 250 mg/L IBA was responded better and survived for two years. Indole-3 acetic acid treated stem cuttings initiated branches within 7 weeks but very few branches arose. The cuttings treated with NAA responded with less relative growth than IBA. This method proves the rooting ability of IBA and growth performance of stem cuttings, which can be used for the mass propagation and conservation of this rare medicinal plant to prevent the exploitation from the wild.

    Opis:
    This paper proposes an efficient in vitro propagation method for a red dye yielding and medicinal herb - Oldenlandia umbellata L. The plant is well-known in Siddha medicine for its styptic property. It is also used as drug for bronchial asthma, as a febrifuge and to treat poisonous bites and ulcers. Moreover, the red dye from its roots has been used in diverse applications since ancient times. These varied applications have increased the utilization and exploitation of this plant for medicinal and dye extraction purposes. Hence, a protocol for rapid propagation is standardized in the present study. Herein, the nodal and internodal of Oldenlandia umbellata L. were cultured on MS medium supplemented with cytokinins, 6-Benzylaminopurine (BAP), GA3, Kinetin (KIN), and auxins 1-Naphthaleneacetic acid NAA, 2, 4-Dichlorophenoxyacetic Acid (2, 4-D). Direct organogenesis was the intent. In doing so, the nodal and internodal explants showed maximum number of shoots in the combination of 2.5 mg/l BAP, 2.0 mg/l GA3, 0.5 mg/l. In addition, the explants growing on medium supplemented with 10 mg/l BAP was found to have generated more shoots. The developed shoots were then transferred for rooting to half strength MS medium fortified with IAA, IBA and NAA ranging from 2-5 mg/l. The best results were achieved on 2.0 mg/l 89.6 % (IBA) Indole-3- butyric acid. For hardening, the rooted plantlets were subsequently transferred to paper cups containing FYM, red soil and sand in the ratio of 1:2:1. They were then transferred to the growth chamber for acclimatization. After acclimatization, the plantlets were transfer for further development under field conditions. About 95% survival was achieved in the field.
