Abstract
Brazil has established extensive Eucalyptus plantations to support a growing forest products industry. During the past 25 years, the country has been a pioneer in developing clonal propagation systems to regenerate these highly productive plantations. Original clonal selections optimized disease resistance, coppicing ability, and volume growth, while recent priorities have moved to improve volume growth and wood quality. The techniques used for the establishment and management of clone banks has seen fundamental changes during the development of clonal systems. From early clone banks, established at wide spacings over large areas, there has been a gradual shift to intensively managed smaller units. The evolution in clonal techniques has increased planting stock quality and lowered prices. Brazilian industrial programs commonly produce millions of cuttings from tissue culture techniques and intensively managed hedges in green houses. Specific technologies have been developed regarding container medium, fertilization, and environmental management. These technologies are typically produced through cooperative industry and academic programs.
