Elimination of Empty or Blind Coniferous Seed by Specific Gravity Separation

The removal of empty or blind seed in the processing of large lots of coniferous seed is an old problem, mainly because such seed are difficult to distinguish from those that are sound or full. As a consequence, they are not classed as impurities in the seed lots. However, their removal is common practice in processing most agricultural seed. One method employs a specific gravity-separator, commonly called a gravity table. This note presents a short report on the application and results of such separation with a lot of loblolly pine (Pinus taeda L.) seed.
