  1. Derived values include the air temperature modifier (m) averaged over the trial duration and the temperatures at which m = 0.05 in the lower (T b ’) and upper (T c ’) parts of the distribution. Each value shown is the mean of three blocks. For the analysis the F values are given followed by the P-category. Asterisks ***, ** and * denote significance at P = 0.001, 0.01 and 0.05 respectively; ns represents not significant at P = 0.05. Values in a row followed by the same letter do not significantly differ.
  2. 1E. g. = Eucalyptus globulus; E. c. = Eucalyptus camaldulensis; E. n. = Eucalyptus nitens.
