Abstract

In a laboratory study stratification had little or no effect on the germination capacity, but it significantly increased the rate of germination in western hemlock seedlots. The greatest increase occurred after 1–2 weeks of chilling on moist filter paper. Naked stratification in plastic bags produced nearly the same response. For stratification longer than 2 weeks, increments in germination rate became progressively smaller. Excellent germinability was indicated by germination values over 30, poor germination by germination values below 13.
