Table 3.

Genetic (family level) and among-tree correlations for the monoterpenes in deer experiment 2. The top right part of the table shows correlation coefficients of the family means (20–60 plants per family), calculated for groups of half sibs, across the five families in the experiment. The bottom left part of the table shows correlations among individual monoterpenes calculated across all 200 plants in the experiment. Statistical significance is derived from likelihood ratio tests (see text). The mean, maximum and minimum needle concentrations are shown for each monoterpene.
