Application of Radiography to Seed Viability Problems in Yellow-Poplar Seed Orchards

Cross-pollinated samaras from 25 clones in a yellowpoplar breeding orchard were subjected to radiograph and germination analysis. A high correlation was found between filled samaras identified by radiographs and samaras that germinated. Using clones as females, significant differences were observed among clones for percent filled samaras; no such differences were present among pollen parents. Viability tended to be higher when clones were crosspollinated than when the same clones were open-pollinated.
