Influence of IBA on propagating hardwood cuttings of Lagerstroemia indica (L.) PERS

Abstract

The current study was aimed to find the effect of IBA on rooting of cuttings in Lagerstroemia indica (L.) Pers. The experiment was laid out in Completely Randomized Block Design (CRD) with 4 replications, including four treatments of various concentration of Indole-3-butyric acid (IBA) solutions viz., 1000 ppm, 2000 ppm, 4000 ppm and control (without any treatment). Minimum days for sprouting (10.52 days), rooting percentage (95.43%), number of roots per cutting (8.15) and root length (10.56 cm) are recorded maximum IBA 4000 ppm. IBA concentrations 2000 and 4000 ppm are on par with each other and significantly higher than control in survival percentage. From this experiment we conclude that, the rooting and survival capacity of hardwood stem cuttings of Lagerstroemia indica under mist chamber conditions, can be improved by quick dipping of basal portion of cuttings on IBA with 4000 ppm concentration.
