Vegetative propagation in Karanja (Pongamia pinnata L.)

Download this article as: 

The present study reports fast multiplication of Pongamia pinnata through vegative propagation to produce desirable genetically identical individuals. Stem cuttings with varying thickness viz., <1cm, 1-1.5cm and >1.5cm were treated with different concentrations (50,100,200,400,600,800 and 1000ppm) of auxins (IBA and NAA) along with distilled water (control). IBA and NAA at 800ppm showed the best result compared to other treatments. IBA treatment responded better as compared to NAA. Supra optimal level of auxins treatment causing reduction in rooting.
