The effect of cone storage on seed viability during 5 years of storage at 35°F was tested with seeds from studies with loblolly (Pinus taeda L.), slash (P. elliottii Engelm.), longleaf (P. palustris Mill.), and eastern white (P. strobus L.) pines. Results showed that: (1) with the exception of slash pine, seeds from cones stored for the longer periods retained quality during storage better than seeds from cones that were stored only short periods; (2) all species exhibited slight, but statistically significant, decreases in seed quality after 3 years of storage, and with the exception of loblolly, more substantial decreases in germination rate at 5 years; (3) with the exception of eastern white pine, declining rates of germination indicated losses of seed quality at least one year before total percent germination decreased, and (4) slash pine seeds from cones in the center of 20-bushel crates performed better in storage than those from cones at the top of the crates or from cones stored in bags, but storage container made no difference for loblolly.
