Abstract

Guddeim (Grewia tenax Forssk.) is one of the important trees native to Sudan. Despite its economic importance in agroforestry, medicine, and nutrition, little or no information is available on its propagation. The present study is an attempt to report on its production by seedlings and stem cuttings in the nursery. For seedling production, three soil media and three watering intervals were tried. Above ground parameters (diameter at collar, shoot height number of leaves plant and shoot dry weight) and below ground parameters (root length and root dry weight) were measured. The condition for growth was found to be the use of pure river sill soil with daily irrigation for the first six walause six weeks as initial establishment, and watering every four days thereafter under partial shade. For stem cutting propagation, Indole butyric acid (IBA) and Naphthalene acetic acid (NAA) were used. However, neither of the two hormones did improve rooting percentage, compared to the control.
