The effect of temperature and water stress on laboratory germination of Eucalyptus globulus Labill. seeds of different sizes
M López, JM Humara, A Casares… - Annals of Forest Science, 2000 - afs-journal.org
Germination rate and germination capacity of Eucalyptus globulus Labill. increased
significantly with increasing temperature (13$^\circ $ to 33$^\circ $ C) for all seed sizes to an
optimum at 28$^\circ $ 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.

Abstract
Germination rate and germination capacity of Eucalyptus globulus Labill. increased significantly with increasing temperature (13 to 33 C) for all seed sizes to an optimum at 28 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.
