Oji Paper Develops Eucalyptus Trees that Grow in Acidic Soils

Japan's Oji Paper Co. has developed a type of eucalyptus trees that can grow well in acidic soils, by utilizing its independently-developed techniques for genetic transformation of eucalyptus. The company currently conducts afforestation overseas, mainly using eucalyptus because it grows quickly and is suitable for pulpwood production.

Oji Paper Forestry Research Institute carried out this study jointly with Gifu University, and reported the findings at the annual meeting of the American Society of Plant Biologists, held in Hawaii from July 25 to 30, 2003

As rapid global population growth has made food production a top priority, there has been rising pressure to plant trees on infertile land. Afforestation on barren land can also contribute to carbon sequestration. The company, which has been conducting afforestation since 1993, has been developing eucalyptus trees that tolerate environmental stresses such as drought and high salinity. This time the company targeted acidic soils for its research. Acidic soils, which inhibit plant growth, are common in tropical regions, where trees would otherwise grow quickly in non-acidic soils.

Until the genetically-modified eucalyptus proves not to be hazardous to surrounding ecosystems, this research must be conducted in an isolated environment. Further research toward practical applications will be conducted in a large dome facility, called Biosphere, in the United States. After the safety of these trees and the suitability of the wood for use as pulpwood are confirmed and meet standards in the enclosed greenhouse, the researchers plan to evaluate it in an open testing ground. The project proponents aim to begin outdoor plantations within ten years.
