Materials and Methods
Plant material. All material was sourced
from close to Adelaide, South Australia (lat.
34°58’S, long. 138°38’E). Eucalyptus globulus
plants were located on a grower’s property at
Inman Valley. Eucalyptus cinerea and E. albida
stems were harvested from the Waite Agricultural
Research Institute Arboretum. Stems of
E. sideroxylon, E. platypus, E. spathulata, E.
cladocalyx x E. platypus, E. spathulata x E.
platypus, and E. spathulata x E. sargentii were
collected from plantations at Murray Bridge.
The hybrids were the result of a crossing
program (Ellis et al., 1991).
