Age of Tree and Root Development by Air-Layers in Loblolly Pine

Activity in forest tree genetics and improvement has increased considerably during the past decade in the Southeast. Methods of vegetatively propagating tree species are deemed of prime importance as "tools" for needed studies. Among the pines, grafting techniques are sufficiently well developed to allow rather easy vegetative propagation of clonal stock from trees of all ages. This method is now being used extensively for the establishment of seed orchards.
