Influence of IBA and NAA on rooting of Adathoda vasica

Adathoda vasica is a medicinal plant beneficial for the treatment of asthma, cough, haemorragic disorders, hepa-titis and fevers. The leaves of the plant contain a mixture of alkaloid, i.e., vasicine and vasicinone. Vasicine has numerous pharmacological activities viz., anti-malarial, anti-inflammatory, antioxidant, antidiabetic, anti-bacterial etc. The study on influence of IBA and NAA on rooting of Adathoda vasica was conducted during 2011-2012 at Medicinal and Aromatic Plants Research Station, Rajendranagar, Hyderabad, India. The experiment was set up in a complete Randomized Block Design with nine treatments (T) consisting of Indole Butyric Acid hormone (IBA) @ 250, 500, 1000 and 1500 ppm; Naphthalene Acetic Acid (NAA) @ 250, 500, 1000, 1500 ppm and untreated control. These treatments were then designated as T1, T2, T3, T4, T5, T6, T7, T8 and T9, respectively. Results exhibited that maximum rooting percent (67.50 %) and longest root length (22.18) were recorded in T4 (1500 ppm IBA). Whereas maximum roots per cutting (40.89), root fresh (3.22 g) and dry weights (1.12 g) were noted for T8 (1500 ppm NAA). Thus it can be concluded that if rooting of Adathoda vasica semi hard wood stem cuttings treated with IBA @ 1500 ppm or NAA @ 1500 ppm concentration can promote the mass propagation of the said medicinal plant.
