Description: A northeast Washington collection of western larch seeds was stratified for 0,10, 20, 40, and 80 days and incubated at 55, 64, and 73 °F. The germination percentage of filled seeds and speed and uniformity of germination were improved by long stratification, particularly at the lowest incubation temperature. Stratified seeds were also nursery sown in early April and May. Emergence occurred when mean air temperatures were low (48-54 °F), which indicated that long stratification should be beneficial in the nursery. First-year seedling height was closely related to date of emergence.
Keywords: Emergence, germination percent, germination rate, incubation temperature, stratification, seedling height
