An Ultrastructural Analysis of Spruce Budworm-Promoted Defoliation in Abies Balsamea
Balsam fir (Abies balsamea), a transcontinental gymnosperm, is of economic importance for lumber and wood pulp. Forest managers are continually faced with demands to increase wood yield. The problem is exacerbated in the case of balsam fir since spruce budworm periodically severely depletes the available wood inventory.
