Description:
Up to 60 balsam fir provenances were evaluated at five locations in the Lake States at an age of 11 years from seed. Provenance effects were statistically significant at each location and, in general, eastern provenances were taller and produced more branches than western ones, while the initiation of shoot elongation followed a latitudinal gradient, with earliest flushing among provenances from north of 49° N. There were large differences, however, between some provenances from the same state or province. Provenance-plantation interaction was present in all tested combinations of plantations, but no geographic pattern of phenotypic instability was found. The observed results may reflect a geographic pattern of high vigor in eastern provenances confounded by effects of spring frost mediated through phenology of shoot elongation. Certain provenances have the desirable combination of vigor and late flushing.
