註釋

Survival of recently fallen northern red oak acorns after exposure to a cool fall burn was determined on experimental plots in northwestern Pennsylvania. The fire consumed the leaf litter and fine woody material of the forest floor and was considered as a typical fall burn for this region. No acorns were consumed by the fire but some were charred. Between 40 and 49 percent of the acorns contained in the litter were killed. The fire was not hot enough to kill Curculio weevil larvae within the acorns. Burned acorns infested with Curculio that survived the fire had 20 percent lower germination rates than unburned acorns.
