Three provenances of Scotch pine were grown from seed in a greenhouse for 90 days using 9 fertility-moisture treatment combinations (3 fertility X 3 moisture). Swedish and German origins grew at different rates but had similar responses to varying moisture and fertility levels. Both grew fastest at the medium-moisture and medium-fertility level. In contrast, the Spanish source grew fastest at the low-fertility, high-moisture level. Forest Sci. 16:43-45.
