摘要：
Germination rare and germination capacity of Eucalyptus globulus Labill. increased significantly with increasing temperature (13 degrees to 33 degrees C) for all seed sizes to an optimum at 28 degrees C, then decreased. Biggest seeds generally germinated best at all temperatures. Germination was also very sensitive to water potential (0 to -0.75 MPa), with no germination occuring at potentials below -0.25 MPa.
