Propagation of Some Hard–to–root Ornamental Plants by Tissue Culture Iii – Rooting Stage

Abstract

Growing Cupressus macrocarpa shoots on Murashige and Skoog (1962) medium (MS) with IBA at 20 ppm for 7 days before sub-culturing on a medium free of plant growth regulators gave rise to the best possible rooting percentage with only one root/shoot. Rooting percentage of Conocarpus erectus rose significantly to its utmost with indolebutyric acid (IBA) at 5 ppm.
