The treated area was wrapped in wet moss and covered with plastic for several weeks as shown on the twig at the left. This technique, called "air- layering, " will facilitate the propagation of cuttings from "elite" trees. Air-layering a Promising Technique for Slash Pine Rooting It is a well established fact that propagation by vegetative means, such as rooting branch cuttings, assures progeny of the same characteris- tics as the parent. In an effort to develop more efficient propagation techniques for slash pine, intensive studies are under way at Olustee and Gainesville, Florida. Air-layering, an established technique in horti- culture, has now been used with 85-percent success on slash pines 5 to 17 years old. The technique involves girdling a twig, painting the wound with a chemical growth substance, and binding wet moss about the wound with a plastic sheet that has been treated with nutrients and a fungicide. When roots appear (fig. 4), the twig is severed from the tree and planted in a nursery bed for further development. - 10 -.
