Influence of Seed Weight on Early Development of Eastern White Pine

In the Northeast, eastern white pine (Pinus strobus L.) cannot be relied upon to consistently regenerate naturally due to the destruction of the cone crops by the white pine cone beetle (Conopthorus coniperda Schwarz). The white pine cone beetle has been reported to have destroyed the white pine cone crops for nine consecutive years in one area of southern Maine (Graber 1964). Artificial seeding or planting is necessary to obtain adequate regeneration. The objective of the study was to determine what influence seed weight has on one- and two-year-old seedlings grown under two environments. The two environments were: (1) in the field as a result of direct-seeding and (2) in pots in a greenhouse.
