Abstract
Chironji (Buchanania lanzan Spreng.) is considered very hard to root species. The effect of different concentrations of IBA and IAA and their combination on the adventitious rooting of the root cuttings of Chironji were investigated using one year old root cuttings in non-mist propagation chamber. Maximum rooting per cent (90%) was observed with IBA at 2000 ppm. However, there was no significant difference among the IBA and IAA treatments for the rooting per cent. Highest number of adventitious roots (7.34) was recorded with 1000 ppm IBA+1000 ppm IAA. However maximum length of longest root (8.63 cm) was recorded with 2000 ppm IBA+2000 ppm IAA. The study reveals that there is substantial potential for vegetative propagation of the species through root cuttings. The technique can be used in the multiplication and tree improvement programme of the species.
