A Trial To Mechanically Sort Clones From A Bulk Seed Lot
Increasing numbers of organizations are harvesting loblolly pine seed with net collection systems instead of collecting cones. With this type of bulk seed collection, the benefits of genetically uniform seed are forfeited. These benefits include more uniform germination, more uniform spacing of seed on the nursery bed, and ultimately more plantable seedlings per pound of seed. Differences among clones in seed diameter, weight, and color are familiar to anyone who has worked with individual tree collections of seed. A trial was made to determine if precision seed sizing could separate clones from a bulk seed lot.
