In glasshouse experiments, the 4 Eucalyptus species studied did not show the same degree of temperature acclimation observed for N. oleander in this and previous studies. Photosynthetic acclimation to temperature varied with species of Eucalyptus, apparently in relation to their subgeneric groupings. The estimated parameter, the preferred temperature for photosynthesis, correlated broadly with temperature conditions in the natural habitat. Low temperature acclimation was similar for N. oleander and most of the Eucalyptus species and was accompanied by an increase in 2 biochemical parameters. Regeneration capacity was sensitive to low temperature in high-temperature grown E. miniata.
