Comparison of Germination and Viability Tests for Southern Hardwood Seed
This paper summarizes a 3-year evaluation of 10 methods for testing germinability and viability of the seed of six species of southern hardwood. In five of the methods, the seeds were germinated. In the others, visual, biochemical, or physical properties were the criteria. Cutting tests were best for sweetgum and Nuttall oak seed, while cutting or water germination gave equally good results on sycamore seed. Floating was best for eliminating bad willow oak acorns, and floating combined with visual inspection of sunken acorns was best for cherrybark oak. No reliable test was discovered for green ash seed.
