Abstract

In breeding trees for rapid growth, testing the progeny usually requires many years. To shorten the testing period, geneticists have tried to find characteristics in juvenile trees that would indicate mature-tree performance. With hybrid poplars (Populus spp.), work at the Northeastern Forest Experiment Station has shown that the thickness of bark on the roots of 1-year-old cuttings is significantly related to the growth rate of the tree.
