스트로브잣나무의 생장을 산지별, 조림지별로 조사·분석한 결과, 국내에서 가장 우수한 생장을 나타내는 산지는 North Carolina, 가장 우수한 조림지는 춘천이었는데, 측정형질 공히 산지보다는 조림지에 따른 생장의 차이가 큰 것으로 나타났다. 형상비 분석을 통한 수목 생장은 비교적 안정적이었으며, 조림지별로 수령에 따라 매우 다른 양상을 나타냈다. 스트로브잣나무의 생장 강수량, 안개일수, 고도, 토양의 모래함량과 정의 상관관계가 인정되었으며, 연령 간 높은 정의 상관관계를 나타냄으로서 유령기 생장순위가 중기까지 그대로 유지되어 우수 산지 조기 선발의 가능성이 높은 것으로 판명되었다.

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.
