Abstract

Ginger is an industrial crop which has a high economic value. However, the productivity of ginger has been decreased year by year. There are two limiting factors on preparing the rhizome as propagation material: disease that caused by bacteria Pseudomonas solanacearum, and the rhizome for unit of area is in great quantity. In this case, tissue culture hoped to be an alternative tool. It has not find the standard method to discover the rhizome with great quality, great quantity, and resistant to the disease. One of limiting factor to success in plant propagating by tissue culture is composition of media and plant growth regulator. The research studies about the effect of concentration of 2.4-D for initiate of ginger callus in vitro. An experiment was done at Tissue Culture Laboratory of Faculty of Agriculture, Andalas University Padang from August to October 2000. The result indicated that concentration of 5 ppm 2.4-D shown the best composition for callus initiation. Key words : ginger, tissue culture, 2.4-D
