PRODUCING sorghum seed of good quality that germinates well has become very important since the introduction of sorghum hybrids and the resulting rapid increase in sorghum acreage. Early frosts before the seed matures can reduce germination materially. Although most seed production fields are in the Southern Great Plains, early fall freezes may occur even there before the seed matures. This study was conducted to determine the extent that germination is reduced when sorghum seed, at various stages of maturity, is frozen at different temperatures and for varying lengths of time.
