Anatomical Criteria for Early Selection in Poplars

One of the most apparent and serious drawbacks to the rapid improvement of forest trees is the time element; especially the time required for progeny testing or, putting it another way, the time required to grow a tree to the size or age at which its potential can be evaluated. Often times the value of a tree or shrub used for ornamental or fruit production purposes may be judged when the plant is relatively young but many of the important characteristics of forest trees are those concerned with growth and development over an entire rotation. Therefore the most accurate appraisal of growth potential must be based on long-term tests.
