A trivariate summary measure based upon the number of sprouts, the lengths of the sprouts, and the number of intemodes per sprout was developed to compare the effects of growth suppressants on tree regrowth after trimming. A new graphic, the tree picture, was developed to display this information. The tree picture is easy to interpret and revealed clear results for the data given. These results demonstrate how innovative graphical methodology can be applied as a summary device in the absence of or as a supplement to a statistical testing procedure.
