The Initiation and Maintenance of Callus Cultures

Plant tissues grown in vitro provide an ideal research tool for the study of a wide range of aspects of plant science. For example, they have been used in the investigation of both primary and secondary metabolism, cytodifferentiation, morphogenesis, plant tumor physiology, and the formation of plant hybrids via protoplast fusion techniques. Plant tissue culture is also being increasingly adopted for the commercial propagation of plants.
