Abstract
Grafting is one of the standard methods of propagating trees of superior form, vigor and wood properties and bringing them together in clonal seed orchards. The Araucarias have been very little planted in East Africa in comparison with the other exotic conifers, pines and cypresses. This is largely because of difficulties in seed ~apply. They produce a high-class softwood suitable for both saw timberland peeling, and planting of this genus on suitable sites can be expected to expand, albeit slowly. A special reason for attempting interspecific Araucaria grafts has been the fact that the fastest and straightest specIes in Tanzania, the 50-year old A. exce/sa (N orfolkIsland Pine) growing at Amani, produces little or no fertile seed, whereas viable seed of two other species, A. cUllllillghamii (Hoop Pine) and A. columnaris (syn. Acookii) is available in fair quantity in most years.
