Correlations Between Controlled-Environment and Nursery-Grown Seedlings of Jack Pine Provenances

Estimates of genetic variation can be obtained from tree seedlings grown in a uniform environments If sound predictions of adult performance can be made from short-term tests, large numbers of seedlings and seedlots can be tested under stand conditions, and only relatively few selected lots need be carried forward for longterm testing in the field. It was with this in mind that the dry-weight of four-month-old seedlings of a number of jack pine (Pinus banksiana Lamb.) provenances grown in a growth cabinet an in a greenhouse was compared with the height of the same populations grown for 3 and 4 years in an open nursery at the Petawawa Forest Experiment Station. The seed was collected from stands located throughout the geographic range of the species, from the Atlantic coast to the Mackenzie River in the Northwest Territories (fig. 1).
