Yellow-poplar seed remained viable for four winters in forest litter in experimental areas in Illinois and Indiana. Under natural conditions viable seed accumulates for several years and germinates when seedbed conditions are suitable. With proper cutting and a favorable seedbed there is little need to reserve seed trees on areas cut to reproduce yellow-poplar. The study provides some basic information about the germination of yellow-poplar seed. Some seeds germinate in the forest litter without a mineral seedbed, but such seedlings rarely live more than one growing season. Sandflat tests showed that stratification for one winter does not break dormancy in all seeds, but after stratification for two winters most of the seed will germinate if conditions are favorable. The experimental techniques used simulated natural conditions and could be used to study other species.
