        스트로브잣나무의 미국 6개 산지의 생장을 분석한 결과, 남쪽산지인 Georgia와 North Carolina 산지의 생장이 가장 우수하였다. 전체적인 생장의 경향은, 남쪽 산지의 생장이 우수한 반면 북쪽 산지의 생장은 상대적으로 저조하였으며, 잣나무에 비해 평균 2.4배(1.7~3.1배) 정도 재적생장이 우수하였다. 유시생장의 순위가 27년생까지 거의 변하지 않고 유지 되었으며, 이는 우수산지에 대한 조기선발 가능성이 매우 높음을 알 수 있었다.

        The growth performance of Eastern white pine (Pinus storbus L.) was studied with six provenances in four plantations. All growth performances were significantly different among provenances and plantations. The most outstanding source in volume growth at age 39 is North Carolina in all plantations and this trends had been started from four years old seedlings. In plantations, the growth is best in ChunCheon plantation while that is worst in GunPo plantation. The Effect of plantations was thought to be larger than that of provenances growth of P. strobus. A pattern of growth by ages was different by among plantations and even ate age about 40, the growth was still vigorous. Annual precipitation, foggy days, altitude and sand contents in soil are positively correlated with growth and the correlations between by ages were very high.
