Development of Salt Tolerant Eucalyptus Globulus by Selection

Abstract

Selection of Eucalyptus globulus trees, which were excellent in growth and tolerance to aridity, was performed in the Western Australia plantations of Nippon Paper Company. In order to confirm the inheritance of the selected trees in an early stage, the salt resistance and drought resistance of those were estimated by laboratory testing of the cultured tissue and the clonal plantlets. It revealed that some individuals could survive for a short term when the salt contend reached the level of the seawater and the individuals had high drought resistance after watering was stopped. Trial plantations of the clones were started in Western Australia.
