In 1981 white fir and Shasta red fir seeds were stratified for 2 or 4 weeks, dried to 3 moisture levels (white fir – 32%,37%, 38%; Shasta red fir - 26%, 33%, 43%), restratified for 0, 2, 4, or 6 weeks and sown in a nursery. In a similar study in 1982, seeds were stratified for 2 weeks, dried to 3 moisture levels (white fir – 20%, 30%, 40%; Shasta red fir – 13%, 25%, 37%), restratified for 0, 2, 4, 6, 8, or 10 weeks and sown in a greenhouse and nursery. Results indicate that in most cases drying and longer restratification significantly increased total germination or rate of germination. Dried seed, also, suffered less fungal contamination and germination during the restratification period.
