. Seeds of Eucalyptus urophylla and Eucalyptus urophylla were separated in 3
size classes: large (those which did not go through e sieve of round, 0,71mm in diamater
holes), medium (0,59mm) and small (0,50mm). These size classes were compared as to
germination capacity and speed of germination, the results indicating that seed size did
not influence germination capacity and that large and medium seeds germinated faster
than small ones.
