Sprouting and Growth of Orange jasmine (Murraya paniculate L.) as influenced by type of hormone and concentrations

Abstract

Orange jasmine is an evergreen ornamental shrub widely used in landscaping design, it belongs to family Rutacea and is a native to South Asia, Southeast Asia and Australia. However, it is difficult to propagate and this affect the rate of its survival during propagation. An experiment to determine the growth and aesthetic charasteristics of Murraya paniculata L. as influenced by type of hormone and concentration was carried out in the horticultural nursery, Department of Crop Production, Federal University of Technology Minna, Niger State, Nigeria. Treatments consists of hormone types (Indole-3-Acetic Acid (IAA) and Indole-3-Butyric Acid (IBA) at 4 different concentrations 90, 1000, 2000, 3000 mg/l). The experiment was a 2x4 factorial in a Completely Randomized Design (CRD) with three replications. Data collected on growth and flowering parameters were subjected to Analysis of variance (ANOVA) using Genstart 12.0 version and treatment means were separated using the least significant difference (LSD) at (p< 0.05). Sprouting commenced 20 days after planting (DAP) for cuttings dipped in both IAA and IBA hormones, higher number of leaves was recorded for cuttings dipped in IAA(17.25) and those dipped in IBA had the least (15.55). Stem cuttings dipped in 1000 mg/l concentration had optimum pant height, highest number of sprouts, and broadest leaf area. The stem girth of cuttings dipped in 1000 ml is thicker than those dipped in other concentrations. It could therefore be concluded that using IAA at 1000 ml hormone concentration is optimum for good performance of Murraya paniculata.
