The Vegetative Stage of Stock and Scion are Important Factors When Field Grafting Yellow-Poplar

Vegetative propagation of selected forest trees has become widespread. With many species it can be done easily; with others the best results are not satisfactory. Grafting of yellow-poplar, Liriodendron tulipifera L., has been done on a modest scale for several reasons at the Pinson Nursery, Tennessee Division of Forestry, near Jackson, Tenn. Although cambial action begins in the early spring, the rootstock and the scion are not completely joined until the stock has started to vegetate or grow. A late freeze, occurring before dormancy is broken on the understock, can disrupt the union. The grafts can dry out or be weak at the start. Severe pruning at the time of grafting yellow-poplar has ill effects, since the scion vegetation often grows so fast that the union is not strong enough to support it. Also birds sometimes pick off the buds. An abnormal or poorly formed specimen usually results.
