Book excerpt: Excerpt from Effects of Stratification and Temperature on Seed Germination Speed and Uniformity in Central Oregon Ponderosa Pine (Pinus Ponderosa Dougl. Ex Laws.) Germinated seeds were counted on a variable schedule, beginning after 1 day and ending after 80 days in the germinator. Seeds were considered to have germinated when their radicle appeared millimeter long. Counts were more frequent at the beginning of the incubation period when germination was peaking; nearly half of the 50 total counts were made in the first week. Some seeds germinated during the 120 day stratification period, and they were included in the first count. Seeds destroyed by fungi were recorded and removed. Ungerminated seeds were cut open at the end of incubation; full seeds, considered potentially viable, and fungi-infected seeds were counted. The mean and standard deviation of embryo development rate towards germination were estimated for each seed lot by using a procedure suggested by Campbell and Sorensen Rate is the reciprocal of days to germination if a seed requires, for example, 4 days to germinate, its embryo development rate is units per day. Mean rate is the reciprocal of days to 50 percent germination, and standard deviation of rate is the standard deviation around mean rate. We analyzed germina tion data on the rate scale rather than the day scale because the distribution was closer to normal on the rate scale.
