Abstract:

Growth of lodgepole (Pinus contorta Dougl.) and ponderosa pine (P. ponderosa Laws.) under nine different temperature regimes and four levels of soil fertility was investigated to increase understanding of growth rates of the two species in south-central Oregon. Fertilization increased growth of both species under all temperature regimes studied. Lodgepole pine growth was not as sensitive to night temperature changes of 8° to 16°C as was ponderosa pine growth. The number of daily degree hours necessary for maximum growth increased with increasing soil fertility level for night temperatures of 16°C. Forest Sci. 18:132-134.
