Abstract


Reforestation in the arid zone depends on the successful propagation of trees. Vegetative propagation may serve as a good alternative to propagation by seed. This study was carried out in a nursery in Maiduguri, Borno State, Nigeria. The study was focused to determine the effects 4 various concentrations of indole butyric acid (IBA) on the rooting and growth of Delonix regia stem cuttings. The treatments consisted of four concentrations of IBA (1000ppm, 2000ppm, 3000ppm, 4000ppm) and control. The experiment was factorially combined and laid in a complete randomized block design with four replications. The results indicated that application of IBA at 2000-3000ppm compared to 1000ppm and 4000ppm gave significantly (p<0.05) higher results in all measured parameters. Cuttings treated with IBA in respective of concentration gave higher results than those without IBA (control) in all parameters except root number where treated cuttings were at par with control.

Keywords: IBA, Delonix regia, rooting, stem cuttings, vegetative propagation.
