<i>Pinus maximinoi:</i>A Promising Species in South Africa

SYNOPSIS A number of provenance trials of Pinus pseudostrobus initiated by the Oxford Forestry Institute were planted in the Eastern Transvaal Forest Region. Taxonomic studies later revealed that many of the provenances included in these trials were P. maximinoi (previously known as P. tenuifolia) and not P. pseudostrobus. Four-year results from one of these trials indicated that the Honduras and Guatemalan provenances of P. maximinoi had better growth than P. pseudostrobus, South African P. elliottii first generation seed orchard check lots, and Nicaraguan provenances of P. maximinoi. They were also equivalent to South African P. patula check lots. Several P. maximinoi provenances were above average for stem and crown form. Presently the South African forestry industry relies on only three major pine species in the summer rainfall regions, viz P. patula, P. taeda and P. elliottii. These three species constitute 81% of the total softwood afforested area in South Africa. Owing to the promising growth of P. maximinoi, this species will be tested on a larger scale using the Central American and Mexican Coniferous Resources Cooperative (CAMCORE) seed collections.
